Sets the source pattern to a translucent color. This color will then be used for any subsequent drawing operation until a new source pattern is set. The color, and alpha components are floating point numbers in the range 0 to 1. If the values passed in are outside that range then they will be clamped. The default source pattern is opaque black, which is equivalent to the following:
