Detailed Description

This class allows the definition of an RGB color as triplet of 3 normalized floating point values (red, green, blue).

Although Quantity_Color can be technically used for pass-through storage of RGB triplet in any color space, other OCCT interfaces taking/returning Quantity_Color would expect them in linear space. Therefore, take a look into methods converting to and from non-linear sRGB color space, if needed; for instance, application usually providing color picking within 0..255 range in sRGB color space.
