Whats a warm color and cool color

Warm colors—yellow, orange, red and combinations therein—breathe energy, positivity and a sense of sunshine into any room. Cool colors—green, blue and purple—evoke relaxation and calm. Neutrals like white and gray can also lean warmer or cooler depending on their undertones.

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.

Warm colors advance and cool colors recede, affecting the perception of depth. This theory is based upon that fact that the eye adjusts when focusing on colors of different wavelengths. Red light waves have a longer wavelength than blue ones. An image containing both cool and warm colors would demonstrate contrast of temperature or warm/cool contrast creating more complex relationships between the color (warm colors can read cooler against a higher intensity warm colors and cool colors sometimes can advance against predominately warm palette).
