- * Explanation of why changing only the luma looks weird:
- *
- * Consider when you are workings with colours,
- * when you want to change the brightness of a
- * colour, you multiply all parameters: red, green,
- * and blue, with the same value (this is however
- * only an approximation in most cases, since you
- * are usually usally working with colours that
- * have the sRGB transfer function applied to their
- * parameters). This action is the same in all
- * colour models and colour spaces that are a
- * linear transformation of the sRGB colour spaces
- * (sans transfer function); this is simply because
- * of the properties of linear transformations.
- *
- * The reason you change brightness this way can
- * be explained by how objects reflect colour.
- * Objects can only reject colours that are present
- * in the light source. A ideal white object will look
- * pure red if the light sources is ideal red, and a
- * a ideal blue object will pure black in the same
- * light source. An object can also not reflect
- * colours brighter than the source. When the brightness
- * of a light source is changed, the intensity of all
- * colours (by wavelength) it emits is multiplied by
- * one value. Therefore, when changing the brightness
- * it looks most natural when all primaries (red, green,
- * and blue) are multiplied by one value, or all
- * parameters of the used colour spaces is a linear
- * transformation of sRGB, such as CIE XYZ.
