I have been using Wilton gel black to mix gray and black gumpaste (Satin Ice), but it continuously fades into a pale purple color. I spent all morning making Mt. Rushmore for my husband's cake and now all the presidents are purple! Help!

I'm not at my regular computer so I dont' have the links to previous threads but we've been battling this since the 1970's when they took Red Dye #2 off of the market.

black is made when the 3 primary colors are blended ... yellow, blue and red. When 3 PURE primary colors are blended. We don't really have access to PURE colors like labs do. So our mixtures wont' result in pure black.

Primary Color combos:
Red + Blue = Purple
Red + Yellow = Orange
Blue + Yellow = green

If you have purple icing, then you have basically blue and red .... you're short some yellow. Add a touch of yellow to get it back to black.

Likewise if your black turns green (as is frequently posted as a pretty regular problem on here), that means you have basically yellow and blue .... you're short some red. Add a touch of red to get it back to black.

I work the graveyard shift at a hotel at night while going to school full time during the day. My shift is 11pm to 7am.

Thanks! I'll try adding some yellow and see if that helps. icon_smile.gif

If you start with chocolate and add black you (a) don't have to add as much black; and (b) your fading is minimal and you at least fade to dark brown vs. purple or green. HTH! --at least for next time!
