Wish - New sublayer to start with parent layer's color

Would people agree it could be convenient if new sublayers defaulted to the parent layer’s color ?
(Right now it’s always black. Prefer it to be the same or a close variant of the parent)

Hi Thomas -
My guess is that equally many users will still go and change the layer color of the new sublayer as they do with the current system.

I suppose “a close variant” might be more useful to some users some of the time.
I’m adding that as an additional specification to the open YT item RH-4978 - New layers random color.
Note that that particular wish item is from 2009 and I wouldn’t expect this to get any attention any time soon. You might want to look into scripting this if it’s important to you.

Would this be an ok solution to synchronize child layer colors with their parent layer colors?

layerNames = rs.LayerNames()

for layer in layerNames:
    parents = rs.ParentLayer(layer)
    if parents:
        parentColors = rs.LayerColor(parents)
        rs.LayerColor(layer, parentColors)

Aaand you would be correct sir; even for me.
If you really pressed me for what I want and if I were to go back to my scripting days, I would
a) Determine the screen viewport color and derive a contrast factor out of the lightness value
b) Create a dialog that pairs keywords to colors.
c) Have a pertubation value for the saturation and lightness

The user might want the keyword “lights” to always produce a yellowish layer color (but still having enough contrast on the viewport) … or maybe the keyword “curves” to always produce a greyish layer color etc etc.

I would probably try it myself, but ever since I moved in a Javascript direction and developing a distaste for bracketless languages, I kind often forget about scripting.

Thanks for this quick script Martin !
It compains that rs is not defined ?

I take it after running this script it will go ahead and make all my sublayers the same color as their parent after the fact ?

Hi Thomas - add the line

import rhinoscriptsyntax as rs

at the top of the script.
