Change color in a loop with i-variable?

[UrsBollhalder]

Is it possible to change colors (0xff986734 * i ???) in a sensible way in a loop so that the color changes gradually with increasing i-values?

urs

for (i = 0; i < NumOfSteps; i++)
{
     this.data.play == i ? g.setGradientFill([0xffFF1236 , 0, 250, 0xff737170, 0, 10]) : g.setGradientFill([0xffFF5126, 0, 250, 0x98528170, 0, 10]);    
     g.fillEllipse([offset + StepSize * i + 1, (1 + xy[i] + param2[i]), 3, 3]); 
}

@UrsBollhalder I'm working on something similar for me too, If I get something working I'll make a snippet

@ustk Awesome! Thx!

@UrsBollhalder Here's a very limited one (only blue to black) to get an idea

To go further, you'll need to make an hexadecimal parser. Decompose R, G & B, into decimals, iterate, and parse back to HEX. It's not an easy thing, but I reckon @d-healey made one a while ago...

@ustk Maybe you mean this - https://forum.hise.audio/topic/395/example-of-themed-gui/8?_=1630407614214

[ustk]

@d-healey Effectively, that was a while ago

[UrsBollhalder]

@ustk @d-healey Thanks guys. That’ll keep me busy for a while. A bone to gnaw on…

Beautiful! A circular gradient!

Ingenious!

The days of bit fiddling for color manipulation are over:

@Christoph-Hart Awesome. I was just trying to get away from vectors (art of code - trauma ) for a bit, and now you bring the devil into our midst! Awesome!
