Plants are green because their cells contain chloroplasts which have the pigment chlorophyll which absorbs deep-blue and red light, so that the rest of the sunlight spectrum is being reflected, causing the plant to look green . Object that appear blue do so because they reflect blue light but absorb all other colors, so our eyes only see the blue light remaining. When a blue shirt absorbs the energy from non-blue light, it heats up.
