I found a beautiful reference photo of a Jessika rose, taken by valchina612 at the Wet Canvas Image Reference Library. The colors in the rose range from a yellowish to a peach to a coral to a vibrant pink. So far two of the petals have quin. rose and quin. coral touched by a lemon yellow. The gray is the misket applied to keep the whites. Will do my best to get a soft gradation going into the white.
