This App Helps to Achieve Color Harmony Using a Limited Palette - ArtistAssistApp
ArtistAssistApp also known as Artist Assist App is a web app for artists to accurately mix any color from a photo, analyze tonal values, turn a photo into an outline, draw with the grid method, paint with a limited palette, simplify a photo, compare photos pairwise, and more.
Play around with limited color palettes. Select up to 5 colors to be your primary colors and see what your reference photo would look like painted with just those colors. It helps to depict the atmosphere. For example, the lighting in the north is different from the Mediterranean, as are the colors needed to depict this atmosphere.
