Modifies the luminance of a color so it has sufficient contrast with another color. Fully supports dynamic colors.
@param targetColor The color you ideally want returned if has sufficient contrast. This can be nil, in which case a standard content color will be returned. This can be a dynamic color. @param backgroundColor The color the returned color must have sufficient contrast against. This is typically a background color. This can be a dynamic color. @return A dynamic color with sufficient contrast against backgroundColor in all trait collections. The returned color will be similar to targetColor if possible.
