Illamasqua Hype Eyeshadow ($20.00 for 0.07 oz.) is described as a “matte bright yellow.” This is a vibrant, bright sunshine yellow–it has a lot of warmth. There’s a slightly goldenrod tone to it. It’s not as warm or as dark as MAC Goldenrod, but it is nearly identical to Inglot #323. Other shades of yellow I think of are either more neutral or cool-toned or else have a lot of shimmer.
