Yes, you can get and set the color of the shape and pretty much any other
attribute.
Check this for a list of available attributes, and methods to get/set them
import nuke.rotopaint
help(nuke.rotopaint.AnimAttributes)
To set the overlay color of all shapes to red, for example, you can do:
n = nuke.toNode('Your_Roto_Node')
for item in n['curves'].rootLayer:
attr = item.getAttributes()
attr.set(nuke.frame(), 'ro', 1.0) # set red overlay to 1.0
attr.set(nuke.frame(), 'go', 0.0) # set blue overlay to 0.0
attr.set(nuke.frame(), 'bo', 0.0) # set green overlay to 0.0
Or, to get the name and current color of each shape (not the overlay color,
but the actual fill color):
n = nuke.toNode('Your_Roto_Node')
for item in n['curves'].rootLayer:
attr = item.getAttributes()
print item.name, [attr.getValue(nuke.frame(), '%s' % color) for color in
'rgb']
Cheers,
Ivan
