Bug Description

This only to affects debug builds.

Steps for reproducing:
* Open eeschema with an empty schematic,
* Ensure Preferences > Colors > Body Background color has an uniform color (as in r = g = b) e.g. white (r = g = b = 255) or grayish
* Press A to add a component
* Select any part to insert
* Confirm dialog with OK

Assert is hit at

Hi Ronnie,

Thanks for the patch. I think it would be safer, though, to flip the default value of aAlwaysDefineHue and then change the 3 calls in COLOR4D::GetNearestLegacyColor() to pass false.

That way future users of ToHSV() won't fall into the same trap.

Hi Jeff,

thanks for already merging that patch. I follow your advise to change the default parameter and revise all call to ToHSV(). Patch is attached.

On the side of investigating this I found a comment in include/colors.h that the legacy style color.h/cpp is going away anyways. That's now, after all the work invested in gal & eeschema dev, isn't it?

PS: Actually thanks to Thomas for merging ;) But Jeff thanks for the feedback

Only the Eeschema legacy canvas is going away in 5.1. The PcbNew legacy canvas will likely be retired in 6.0.
