:-) Range is [0..1] not [0..255]

Oh, thank you, how embarassing. I correct it to:
color := Color r: 255 g: 0 b: 0 range: 255.

Still the problem remains the same. I tested the code with Color random and only for the post changed to Color r:g:b:.

And some colors are found to be next to „transparent“ for example
color := Color r: 100 g: 0 b: 0 range: 255.
which clearly has alpha 1.0.
