Comment (by yrizoud@…):

I only wanted to bump this as I noticed someone else mentioned the oddity
again (cels, on a PJ post)
For hue, 360° is clearly a more common scale, this may be important for
people who use several graphical tools and transfer / compare colors.

Remember that the Palette screen has only 128 (or 129 ?) pixels for slider
length, so the actual accuracy when dragging slider can't exceed this
number of distinct values. More accurate numbers can be selected by
clicking arrows, which will increase/decrease the numeric value by 1, no
matter the slider's range.


If somebody thinks of changing the precision of S and V sliders from 255
to 100 as well, I'm slightly worried it will makes the RGB -> HSV -> RGB
conversion more lossy. However, even Photoshop doesn't care about
precision under % for S and V (it actually rejects decimals if you enter
them manually) so it may not be a big deal.
Fortunately Grafx2 only performs this back-and-forth conversion when you
actually move one of the HSV sliders.
