CMYK, for starters.

Cyan. Magenta. Yellow. Black. The building blocks of commercial color printing, and the tools of my trade over the last 30 years in the graphic design business. To this day I am amazed that these four colors can combine to produce some remarkable color printing of astonishing fidelity given the limited source palette. For this drawing, as an exercise, I played with the idea of working with these limited colors and simulating what commercial printing does: produce a final that is perceived to be varied in spectrum, contrast, and intensity, despite a limited source palette. I followed my usual working method of blocking in color over a simple form sketch, with yellow for the highlights, magenta for the mid tones, and cyan for the shadows (see Step1 in photo).

Similar to color printing, I used black to provide contrast and definition. In theory (here), cyan, magenta, and yellow alone should be able to produce a credible simulation of the full spectrum. However, given the limitations of printing ink, paper whiteness, and viewing light, the black is necessary to “punch it up”. And so, I did the same, adding black over the color areas (Step 2 in photo), to darken where the combination of cyan and magenta were incapable of producing the necessary contrast. I worked the cyan and magenta together, one over the other to darken each in their respective areas. Ok, with a little orange to transition between the magenta and yellow, the combination of which in pastel anyway, produces a peculiar pink unwanted here.

For the final, I wanted to thin out the highlights a bit so that the yellow was not so intense. I buffed it down and then came over with some light beige and tans, working them into the background and then re-establishing the yellow where necessary. I wanted a high contrast, but I didn’t want the shadow areas to be too “black black”, but rather, a “colored black”. I scrubbed down the black chalk and worked deep blue and purple together, plus a little green to muddy things up. Not true CMYK, but less stark. I reserved the black for the final definition of forms, where absolutely necessary. “Punching it up”, in my own way.


A couple of production notes: I worked from a black and white image. Or at least the print-out is, I may have stripped out all color from the original at an earlier stage, I can’t remember. The paper is my standard, Rives BFK, but in a hard-to-find size: 30 x 42”, which leads me to believe the sheet may have been cut from their standard 42” wide roll.
