Hey, great idea! I'm sure you've played around with the placement of each color and this is the best one. I am trying to imagine the picture instead of (grey, orange, green, pink, yellow, blue) with (gy,o,gr,b,p,y). What might be another option beside the grey-tone? I don't know... Just thought I'd post a responce. I hope the piece turns out well!

I was actually going for a CMYK vs RGB layout but she didn't like that.

Thanks for commenting!

I love it, I'd have a mauve and a purple, but my own choice to each her own or his.... I have several close ups blown up of my favorite flowers in my home, nothing like this, very, very nice:) Leslie
