Purple/Yellow Moses-Botkin Challenge May 2010

We never quit amazing me! Artists, that is. This month's challenge was the brainwave of Robin Cheers...Do a painting with only two complementary pigments, in this case, purple and yellow (white allowed but no black).

I used Cobalt Violet (Grumbacher Artist's Quality) and Cadmium Lemon (WinsorNewton Artist's). In retrospect, I wish I had used a stronger purple because my darks were limited. BUT, it was a great exercise to know my dark purple was as dark as it could be, so to get more value range I had to use more yellow and white. And, WHY didn't I think to MIX my purple. So typical of me...must have been my left analytical brain in control!

Hmmm. wonder if my cohorts kept their purple mixtures constant...? And if so, fully mixed...? Otherwise, you could go to the red side or to the blue side and still be 'purple', but would yield a few more 'tones'. Of course, most tubes are 'admixtures' in the first place.  My chosen purple contains a cobalt (Pv14) and a Manganese (PB16). It is always interesting to be aware of what is in your tube although I am not a chemist and don't have a clue where the red is coming from!

Very fun work on this challenge Vicki. And you brought up a good point about keeping the mix (purple) stable. I did. And it limited me I think. Its also good to think about the actual tube colors and what is in them. Some lean towards the cool or the warm side, though we might have a blue and think, well, thats cool obviously. But, it can be deceiving!

Great challenge topic! I enjoyed it.


What a fun challenge this month! Your vase is really wonderful, especially that marvellous translucent color of glass right at the focal point where the highlight is! WOW! Your use of background repeats the fluidity of the vase so nicely, too! Jeanne

I tried several mixes for purple before deciding on mine (ultramarine and thio violet). I liked the darks and pure color I could get with my mix (and yes I mixed up a batch to use for the whole painting).

I chose cadmium yellow medium for my complement (warmer and more opaque than hansa).

And yes, blues can be cool or warm, as can yellows.

I love what you've done. It's so interesting to see what different purples we all came up with. This is an incredible painting!

thanks guys! I sure had fun with this...Suzanne, you are over the top. Do you ever do a painting that you are happy with? I keep seeing a white caterpillar on the middle of the vase!
