Yellow BIke In Progress

Had started this 30x30 painting with a burnt sienna toned canvas, using a palette of cad red, alizarin crimson,ultramarine blue,cad yellow and titanium white. After doing the challenge seen on my previous post, I decided to use the burnt sienna as my red, and ochre as my yellow. I'm liking the range of greys,warm and cool, and will hold off introducing any of the cadmiums as long as I can. I am so in love with color so this is a challenge in itself; will see what direction this goes in.....!!
