Once upon a time, graphic design was done using designers guaches… guaches are water based paints, that can be ran through an airbrush, painted thick like water colors, thinned out and used as water colors, they can go down super smooth or blotchy. you can wash them off of your board and reapply them… they were the standard for the graphics industry before the computer came along. if you wanted a color rendering, you used guache…. then maybe something else if they didn’t do what you wanted… now guaches have a dull finish when they are layed down, they dont get thick like an oil painting, and the color isnt as rich. but they reproduce and photograph really well, they dry fast and you can blend the paint by using slight pressure and a moist brush, to achieve a really smooth gradient. they were used for quick layouts and color mock ups, type treatments, architactural reanderings, lettering, just a ton of stuff,
minutia about painting… sorry casey you are probably bored by this stuff…!
