Materials, including <u>pigments</u>, only <em>absorb</em> certain wavelengths. What they <em>reflect</em> defines the color.
Ex: A royal purple purse containing pigments from snails <em>absorbs</em> all colors except for purple, which it <em>reflects</em>, so it appears purple.
A chlorophyll <em>absorbs</em> all colors except for green, which it <em>reflects</em>. <u>So chlorophyll appears green.</u>
