Colosseum (gray white) vs. Heathered Gray (light cool gray)

I got the sample of the Cobblestone and painted an extra cabinet we had. We want a lighter grey for our kitchen. We feel like the Cobblestone is great, but would love a shade lighter.
I'm not sure what to go with. The Colosseum and Heathered Gray look the same.
We don't want white, but when I look at Cashmere (true white) it looks like a light gray - but states it is a true white.

Anyone use any of these or have pictures to help?

TIA!!
