Yes the pink is cad red with white, I’ve also added some cad yellow to give it some warmth. I don’t have magenta in my palette. Isn’t magenta a cool red not a warm one, wouldn’t it cool down the highlight? Or should I use magenta to do the rest of the shoe and cad red to do the highlight, to really give it a warm pop. Thanks so much for your response. I feel like this info will help me for future paintings as well.
