What undertones does requisite GREY have?

Requisite Gray is a light/medium toned color. It has enough pigment so it won't get washed out in a room with lots of natural light. It has a mix of subtle purple and warm undertones. This color is also very flexible in terms of which white you choose.

Why does Gray paint look purple?

Since purple is a combination of blue and red, warm yellow or white light helps to mute the blue tinge in a purple-gray wall, making it appear more gray. Compact fluorescent bulbs are now available with lower light temperatures labeled as "warm white." They provide the same light quality as incandescent bulbs.
