White cake for better colour?

[sowaddayasay]

I want to bake a blue cake, should I use a recipe with egg whites only (and maybe trex?) to make a white cake in case blue paste +
Yellow cake = green? Would that taste a bit wrong?

I think if you use a good gel colour it will be fine with normal cake mixture - I can't see egg whites only making an edible cake TBH.

It is often the butter/stork that causes the yellowness in cakes but if you beat the sugar and butter long enough it will go white, then the cake should be pale enough to take any colour. Gels definitely make better and stronger coloured cakes.

Thank you moaning and blueberry, butter and eggs it will have to be!

I made a rainbow cake using eggs and butter and my blue section was a perfect bright blue using gel colours.

I used dr oetker gel colours (the only gels available in the supermarket) and my blue turned a brilliant green and the red a soft pink! That's despite using the entire little tube... I guess they are not very good gels, at least it smells nice, jut took it out I the oven.

Sometimes it isn't helpful to think of things as 'wrong'. Your cake sounds

I got mine from Jane asher's website. Pricy but they last forever

That's an intriguing comment SirEdmund!

Get sugar flair there professional colours, I made my blue cake with those
