This app calculates various differences between two colors, each specified by L*a*b* or L*C*h coordinates.
In addition to simple differences (such as ∆L*, ∆H*, etc) this application calculates the following color differences:
CIE 1976 (original standard)
CIE 2000 (current standard)
CIE 1994 (two variants)
CMC 2:1 (two variants)
User can enter L*a*b* or L*C*h values and set the number of decimal places from 0 to 4. User can also swap colors (e.g. to verify the formulas commutativity) and enter random colors (to become familiar with the calculator).
