Dayglo is described as a “transformer shade, iridescent white.” It’s a green-tinged white with a green-gold iridescent sheen. It had good color payoff and was mostly opaque. The texture was soft, a smidgen powdery, but smooth and blendable. Dior Dulcinee #2 (LE) is very similar. Dior Peacock (434) Eyeshadow #3 (LE) is slightly warmer. MAC Zestful is greener.
