EXPLORE COLOR LIBRARIES
Browse Chinese and Japanese traditional colors, ready-made palettes, and gradients. Find the closest library colors to a color value you enter.
PICK COLORS FROM PHOTOS
Extract four colors from a photo, or use the photo picker tool to sample a specific point. Combine sampled colors into a palette to save or share.
