A BUG: in the Color Picker Tab of the Palette Panel?
Posted: 24 Jan 2013, 04:19
Test with either APenColor or BPenColor selected:
1. Select the Color Picker tab and notice how it works...
2. Press the stylus anywhere in the rectangle modifies only value and saturation but keeps the hue constant.
3. Now move the cursor up, against the white edge, down against the black edge or over to the gray edge and lift your stylus - this sets saturation to zero and sets lightness to 255 or 0 or somewhere in between, supposedly leaving the hue value set wherever it was on the spectrum (green for instance).
4. The bug: Finally, click anywhere inside the rectangle to select a new saturation and lightness. Unfortunately this seems to force the hue value to jump to 0 (red)…
Hue should resume the same value as before shouldn't it?
I understand that with white, black and gray there is no hue, BUT when you re-establish value and saturation again by clicking within the body of the color picker rectangle, it is disconcerting to have hue suddenly appear as bright red, losing whatever the previous hue was.
When I am working with selected hues in the APen and BPen slots, adjusting their value and saturation, and I need white, black or gray, then want to return to previous hues, I would expect to be able to so.
Is this in fact a bug or just an unavoidable consequence of the way hue, value and lightness is calculated in the picker panel?
