25// Represents a color in the RGBA color space. This representation is designed
26// for simplicity of conversion to/from color representations in various
27// languages over compactness; for example, the fields of this representation
28// can be trivially provided to the constructor of "java.awt.Color" in Java; it
29// can also be trivially provided to UIColor's "+colorWithRed:green:blue:alpha"
30// method in iOS; and, with just a little work, it can be easily formatted into
31// a CSS "rgba()" string in JavaScript, as well.
32//
33// Note: this proto does not carry information about the absolute color space
34// that should be used to interpret the RGB value (e.g. sRGB, Adobe RGB,
35// DCI-P3, BT.2020, etc.). By default, applications SHOULD assume the sRGB color
36// space.
