The interent killed it self while it was being loaded.

Gouache is my favorite medium to paint, while good 90% of the FAC members haven't even heard of that word. I can say, with confidence that some people were born to use that medium. (I'll start finger pointing later...)

Q: so, what IS Gouache?

A: Gouache is non-transparent watercolour, it works just like watercolor and can be used as such, although, if used thinly, the colors aren't as bright as "true" watercolor.


Q: How do you use this medium?

A: You've all used Tempera paints at school, right? just like that.


Q: by non-transparent, do you mean that putting one color on top of another completely replaces the color?

A: Yes, and no, you see, some colors are naturally more opaque than others, browns, greys and blues come to mind. Other colors might let some of the base color show through, so subsequent coat might be needed.


Q: Why use Gouache? why not acrylic paint or oil paints?

A: This is the fun part:

1.Gouache is economical because it can be used on watercolor papers, instead of canvas like the other two.

2. Gouache paint leaves dry, matte surface that can be refined with pastels or colored pencils, unlike acrylic which leaves a glossy plastic coat, or oil paint that takes a week to dry.

3. Gouache dries slower than Acrylics, and can be rewetted easily with water.

4. Gouache can be mixed with all watercolor mediums AND acrylic mediums.

.......

Q: What brush do you use with Gouache?

A: I used to use watercolor brushes, those worked fine, but recently, I bought some stiffer acrylic brushes and I've never looked back. Although Gouache IS technically watercolor, brushes made for acrylic is more suitable.


Q: Is Gouache expensive?

A: Not at all!, I mean, the ones I use, Winsor & Newton Gouache offers 14mL of paint at $6 ~ $12 American. It is more expensive than Acrylics by volume, but since it is closer to watercolor, and has less binding than Acrylic, it last a long time. There is a beginner's set, made from Reeves, that is just as good, but doesn't come in individual paint tubes.


Q: If Gouache is so good, how come I've never heard of it before?

A: Gouache was originally a designer's tool, and still is. Normal Artists preferred acrylic to gouache because acrylic "lasted longer". There is no such thing as lightfast purple in gouache, but since it will be scanned and the original will be kept off the direct sun, I see no problem.


Q: What colors do you recommend if you're buying colors individually?

A: Yellow and Blue don't make green, green color in two primary colors survive while the two colors "kill" each other. 3-color paint theory is one of the biggest BS I've ever heard in my life. Instead, you need six.

W&N colors.

1. Yellow leaning towards blue : Lemon Yellow
2. Yellow leaning towards red: Spectrum Yellow
3. Blue leaning towards yellow: Winsor/Primary Blue
4. Blue leaning towards red: Ultramarine
5. Red leaning towards blue: Primary Red
6. Red leaning towards yellow: Flame Red

Also, convinient mixtures/tones:

1. Permanent White
2. Ivory Black
3. Naples yellow (good base for skin tones)
4. Yellow Ochre
5. Burnt Sienna
6. Winsor Green

With these 12 colors, I promise that you don't have to buy anymore. I use only these and one violet just because I like that color Razz

"Brian-sama"? Egotistical, ne?

Anyways, this has been bugging me for a while, but... how exactly do you pronounce "gouache"?

(And also mail me a tube of gouache so I can try it out Razz)

It's pronounced as Gwash, one syllable. yes, they wasted three vowels to make that sound, if you want to complain, go to a French embassy nearest to you. Smile

Changed the tutorial because the last one was f**king ugly, I found out that pastel fixative darkened gouache... after 2 years of using them together... yes, I'm dense.

It's expensive, that's what it is. Perhaps not if you're buying it for hobby purposes and don't need much, but I've got a supply list for next semester of particular brand/size/and color that is going to be a mighty big bill.

Primary color theory is perfectly possible (well, should be 5, black and white...although you don't need the black). If the colors aren't turning out right, it's because you don't have true pigments. Meaning, you're trying to make orange out of a red that isn't TRUE red, it has small bits of blue in it, so it becomes a muddy green. But if you buy the true primaries, it's perfectly possible to make all the colors you need. HOWEVER, it's much harder than just buying more colors.

But it's not BS. Don't bash my color theory course. Razz

Personally, I use ultramarine, cadmium red, and cadmium yellow when it comes to proper winsor and newton paints. Mostly I use craft stuff that just has names like "red". :lol:

You can put acrylic on literally anything if you gesso it first, by the way. Paper and wood without gesso. Wink Try it. It's cheap-tastic.

... I recommend to you the book...


"Blue and Yellow don't make Green" by... forget her name...


anywho, this book was like, a punch to my belief.


anywho, once again.... I don't think it's that expensive, gouaches have almost pure pigment... like watercolors... except gouache is cheaper by volume since pigment doesn't have to be finely grounded. I'm guessing tube of gouache (14mL) can cover the almost same amount of space that a tube of Acrylic can. (60mL) since most of the weight in acrylic paint is the binder... and, I prefer gouache because it can be rewetted and doesn't ruin your brush... (and don't need complicated mediums)


anywho, try it! It's definately my favorite medium, but I don't see people using it much... Sad and try to ignore my mediocre tutorial... I've been using it for a year and a bit now... god knows I need practise.

Please point me to where I said it was more expensive than acrylic. What I said was that I have a LARGE list of colors that I must buy for next semester in specific brands and sizes, and that list is expensive. Not that one tube is expensive in comparison to something else.

And I have tried it, several times, have several colors of it already that just don't fit the list.

And primary color mixing IS possible. Is it perfect? No. But I've done countless exercises in taking pictures, cutting out a square, and painting in that square using only the primaries. I can do perfect matches/renderings. You'll never mix a perfect pthalo green, but you should never use colors straight from the tube anyway. They're all just starting points.

True yellow and blue will make green. They will not make ultra bright neon tube greens, but there's very little need for those. Not saying you shouldn't use additional colors, merely that you don't have to.

oops.

Primary colors do give you nice secondary and tertiary colors, but the six-color theory explains that every pigments, since they are not like monitor lights where the light frequency can be adjusted perfectly... shows all colors of the spectrum, but only the dominant one shows, and other colors co-exist, if you would make a graph of what color of the spectrum is reflected, every saturated color would give you a bell-curve, highest on the color you see.

If primary red (semi-dominant violet and semi-dominant orange) is mixed with primary yellow (semi-dominant green and semi dominant orange), the color orange is left as result since it is really the only color shared by both pigment... however, the color is somewhat dulled as the result of having "influence" from the greens and violets...


so another way to do it is "halve" each primary colors into two, using quinacridone or alizarine (red with strong violet dominance) to mix with ultramarine (blue with strong violet dominance) to make purple, and ditto for the other two secondary colors, and it is logical to use cadmium red and phthalo blue to make dulled purple.




yeah, two schools of thought for mixing... :ph34r:

EDIT: I'm tempted to make a thread about this, but it seems like not a lot of people will be into this.

EDIT2: I just rhymed (not really) myself...

And those "dulled" colors are often more appropriate than those who paint grass with bright pthalo green. ;)

Which that whole quote basically illustrated my point that three color mixing is correct, but the pigments are not perfect (and far from perfect if you don't use pure primary and instead something closer to magenta, even if it says "red").

yeah, three color theory is perfect if the light frequency can be managed... like the computer screen and other electronics.... however, the pigments are never perfect.

Why would you want a perfect green or orange or purple? What I'm trying to say, is in painting, yellow and blue DOES make green. It doesn't make PURE digital green or perfect pthalo green that can be carefully manufactured by a machine, but you shouldn't paint with those anyway. It makes things look boring and fake.

I think just for the assuring feeling that pure color CAN be achieved, because colors only get duller than the primary color used in mixing. ...although haven't seen pure colors in standard paintings...



An Art project I think that COULD use pure colors are... maybe, a modern art portrait of someone in color halftone? (with acrylic?) using overlapping circles of the three colors and black on white background... other than modern art like that, I don't see much usuage either.

Still don't need it. Most of the halftone stuff is done with primaries and varying amounts of the dots of primaries to visually blend into other colors.

There's a very very tiny use for "artificial" colors in abstract/modern art, but even then it's a poor choice on the artist's part. Pure colors like that are visually boring. It's the same reason that no matter what the project is, good painting teachers won't let you use a single color straight from the tube (and often no black at all, even for mixing).

There's nothing wrong with purchasing more colors, I just don't think you have to for all your painting needs. Razz

I just found out today that gouache = tempera.

Which means I've been using that stuff since third grade. :lol:

It's pretty good stuff. Always liked it more than acrylic. Not very efficient for craft painting, though. :/

gouache pretty much implies all water-based paints that's opaque. : /

but the school grade "gouaches"... makes me want to die :(

Well, they have to save money. XD

I've only used school-grade, sadly. :(

I've still done some decent stuff with it, though. :3

Gouache <3


I've been using acrylic in school a lot (artist grade too, OMFG) and gouache resembles non-glossy acrylic and slightly chalkier, is that a vice you ask? Since Gouache is not glossy, it can take pastels, pencil crayons and even markers over top, making mixed media possible. :3

I still think those things are only possible when you're working on something like paper.
