Combining Warm and Cool Colors It’s also possible to combine warm and cool paint tones in one room in order to create certain effects. Just keep in mind as a rule of thumb that as you move closer to red on the color wheel, cool tones become warmer.

Red light has longer waves, with wavelengths around 620 to 750 nm. Blue light has a higher frequency and carries more energy than red light. The wavelengths of light waves are very, very short, just a few 1/100,000ths of an inch.

Warm colors include red, orange, and yellow, and variations of those three colors. Red and yellow are both primary colors, with orange falling in the middle.

What Are Cool Colors? Cool colors are shades of green, blue, and purple. The only primary color is blue, so any hue with a blue undertone is considered a cool color. They’re called cool colors, as opposed to warm colors, because they are evocative of water.

Determine your undertone color Warm whites have an undertone color of yellow, orange, and red, and cool whites have an undertone of blue, green, and purple. Warm whites will be easier to blend with cream and beige, and white cool whites will mix best with shades of gray.

Warm colors are vivid and energetic, and tend to advance in space. Cool colors give an impression of calm, and create a soothing impression. White, black and gray are considered to be neutral.

Warm & Cool Colors Warm colors — such as red, yellow, and orange; evoke warmth because they remind us of things like the sun or fire. Cool colors — such as blue, green, and purple (violet); evoke a cool feeling because they remind us of things like water or grass.

It can be risky to mix and match whites as one can EASILY make another look dirty/warm/cool/etc… If this concerns you, then stick with the white you already have in the room. If you don’t know the name of the white you have, take a cabinet door/piece of trim to the paint store and have them colour match it for you.
