Besides the formula, Solar Power is a bright, mustard yellow with subtle shimmer. I know this, because when I asked my husband what he thought about my nails, he said, "They look mustard-y." ☺
Solar Power is very bright and fun, and it definitely puts me in the mood for summer. However, I wish the formula was more user-friendly. Until I find a better yellow, this one will live in my stash. ☺
What do you think? Do you like yellow nail polish?
