IR Rainbow 900P is light creamy champagne that flashes light/medium pink. Although I liked the color when I bought it, I wasn't sure how often I'd wear it. I began wearing it regularly, and it became a staple. It works with so many different colors. I really love it with Shu ME Silver 945, grayish purple, bronze, plummy and grayish browns, taupe, gray and green. I also like to layer it over other shades to make them look a little more special. I think 900P is versatile and fun because the creamy champagne gives it a neutral base, while the pink iridescence keeps it from looking drab and ordinary. I have a hard time wearing eyeshadow with pink in it, but not this one. The creamy champagne in the shade and sheer but buildable coverage help make the pink look attractive on me. To anyone who also has a hard time wearing pink e/s and would like to find one that works, check out this gem. There is a minus though. While 900P performs very well, it isn't as soft and smooth as my other Shu eyeshadows.
