Hi Michel,
Some operations should be compatible with the "color" command, in particular
all BEGIN/END operations, as long as there is no COLOR operation. Only those
which have the color as part of the operation arguments (like CYLINDER and
TRIANGLE) won't be recolorable.
Example:
from pymol import cgo, cmd
obj = [
cgo.BEGIN, cgo.TRIANGLES,
cgo.VERTEX, 0.0, 0.0, 0.0,
cgo.VERTEX, 1.0, 0.0, 0.0,
cgo.VERTEX, 0.0, 1.0, 0.0,
cgo.END
]
cmd.load_cgo(obj, 'foo')
cmd.color('blue', 'foo')
Cheers,
Thomas
