Re: [TCLCORE] Tcl 9.0.4 Release Candidates

[Marc C. <cul...@gm...>]

I can confirm that the script prints 0 0 245 on an m3 macbook air running
macOS 26.

However, that result is not exactly wrong, or not in the way you might
guess.  The Apple ColorPicker.app also reports the color as (0, 0, 245).
So Tk is reporting the actual color showing on the screen.  Perhaps this
has something to do with which colorspace is being used when doing the
rendering.
