Yup, sorry, I was too tired yesterday. :-) If you don't want to
check for none then you may want to try my slider style.
Otherwise:
rgb: frame 50x50 [
rgb/color: to-tuple reduce [
any [red/data 1] - 1
any [green/data 1] - 1
any [blue/data 1] - 1
]
show rgb
]
assuming /data goes from 1 to 256 (so you can solve your problem
with black being 1.1.1).
Regards,
Gabriele.
