When it comes to red tones I like to buy a base colored fondant. The reason being that if I start with white the taste and consistency of the fondant will change. All computers have different RGB colors so everyone will see a different hue than what you see on your computer. Your best bet is to match the color with the Pantone color card and let us know the color number (assuming we have all have a pantone color card right?).
It seems to me that the color looks looks like a fuschia color. If so, the color is achieved by mixing red and purple. It is easier to start with a light red base and add purple. However I have yet to find a nice true purple gel!! So start with red and add magenta (intense dark purple/pink) little by little until you get a shade lighter than you need. Let it sit overnight to make sure you get the right color. Red base gels are tricky and become darker the next day. Good luck! Let us know how it goes.
Oh I forgot to say if you use ChocoPan they can match the color you need!
