Re: What's up with the RGB method?by baku (Scribe)

Taking a stab in the dark...
It may be that the colours are on a 48-bit scale in stead of 24-bit; that is, 16 bits are available for each channel (red, green, and blue).
This is becoming increasingly common in anticipation of 48-bit consumer-level hardware, ie: pretty soon you'll actually need the extra bits, and be glad that they're there.
If this is the case here (but I don't know Tk, so YMMV), the range would be 0..65535; everything else should remain unchanged. Try grabbing $widget->rgb('white') and $widget->rgb('black'), and using their triplets as the limits of your sliders:
That's probably overkill, though, since you can generally assume that black will be (0,0,0), which reduces the final block to
There's also probably a right way to do this that I don't know about... :-)
