An RGBa is specified via a function style rgba(r,g,b,a) value, where colors r, g, and b are specified as a decimal value from 0 to 255 or a percentage from 0 to 100%, and the alpha channel value for defining opacity is a number between 0 (fully transparent) and 1 (fully opaque). Values outside this range will be rounded up or down to fit the closest value.
