Color mesures by expression in a line chart

[PeterCaesar]

Hi there,

I have a line chart with 1 dimension (A) and 3 measures (B,C,D). How can I individually color the measures by expresssion. Conditional statement in the color and legend section with rgb or hex code didn't work. If I try to use the measure's expression the line becomes flat e.g.: If(A > 0, rgb(255,99,71), rgb(255,255,255))
Any ideas? 
Thanks,

Peter
