| 2D doesn't do alpha, however, if you've got blitz3d you can create a 2D game and add 3d alpha sprites on the top. |

| Here is some routines I did: http://www.blitzbasic.com/codearcs/codearcs.php?code=343 Also look in the Graphics section for some other routines which will probably help: http://www.blitzbasic.com/codearcs/codearcs.php?cat=1 |

| If its not a ton of graphics that you want to do alpha on, you could use read-/writepixel to read the screen and blend the colors of the image in. For smaller sized graphics this can be done realtime. |

| Im tryin to do a color change... Like when say in Super Metroid when samus charges here weapon she glows red.. thats what I need.. |

| How about just making additional sprites and switch between them depending on the mode the character is in? |
