I recommend a toned-down pink eyeshadow.

Mono Eyes M36 as a cool summer eyeshadow

I recommend Lovely Day.

It has a toned-down pink shade, so it applies with a cool tone.

The swatches above are Classic Recipe and below are Lovable Day.

It is a toned-down light pink color that gets brighter the more you apply. The pink undertone is stronger than in the photo. It isn't warm, so I recommend it as an eyeshadow for cool-toned skin.
