See inside; this doesn't use the pen, only stamping. This script is able to stamp a sprite in any single RGB color with only one costume. Since I'm not aware of any successful attempt to do something like this before, I have no idea if this is an efficient method or not. One of the main reasons for doing this is that the pen can be set to arbitrary RGB colors, which was a major reason to use the pen over stamping. With this method, and (if I'm not mistaken) the greatly increased stamping speed in Scratch 3.0 and removal of Stage3D, stamping should now be a much more viable alternative to using the pen when rendering text, which is mainly what I'm concerned with. If you see this produce an incorrect result that is not merely a rounding error, please comment the RGB value you used. Issues: - Fringing may occur on semi-transparent edges - Probably not an optimal solution - Might be broken in the future if effects are changed in any way - Doesn't work properly with forkphorus
