I must say that I didn't so much "struggle" as just not enjoy the first process of laying down areas of color. Laying down sections of color as a first step makes me uncomfortable. I always wonder whether I want hard edges or soft edges, high contrast or low contrast...etc. This time I ignored my thoughts (crazy as they may be) and really just put down paint to deal with later. That being said, once I started the mark making and emphasizing the color areas I loved this exercise!
I am disappointed that overall I did not get much variation in the yellow and will work on that in the future. The pinks and oranges, however show a wide range of hue and saturation.
I played with hard and soft transitions here and I like having both in the same painting.
All in all, I found this a very successful exercise that made me look to create variety and contrast within my color choices.
