Hello Houzzers

I have a question that I'm not even sure how to ask. We love the warmth of Classic Gray oc-23 but want a slightly lighter version of it.

I don't know how to achieve this: tweak the color composition (I wouldn't know what to tweak and by what percentage) or try another color altogether.

Any help/suggestions/advice would be greatly appreciated.

This is for a cabinet color in a north-facing room.

Thank you very much!
