Issue visualizing mesh with colors in compas ghpython

I can't manage to correctly visualize a mesh with colors using compas ghpython in Grasshopper. Using Rhino, the artists work correctly but in ghpython different colors passed to the `draw_faces` or `draw_vertices` do not seem to have an effect. Am I missing something here?

**Expected behavior**
The mesh, mesh faces, and mesh vertices drawn in different colors.

**To Reproduce**
Rhino 7.15
compas 1.14.1

```
import compas_rhino
from compas_ghpython.artists import MeshArtist

rhinomesh = compas_rhino.conversions.RhinoMesh.from_geometry(inputMesh)
compasmesh = rhinomesh.to_compas()

artist = MeshArtist(compasmesh)
a = artist.draw_faces(color=[0, 0, 255], join_faces=True)
b = artist.draw_vertices(color=[0, 255, 0])
c = artist.draw(color=[255, 0, 0])
```
