Fontweight of color labels prevents saving as SVG #39
Description
When passing label to mp.ColorMesh or mp.Colors and saving as SVG I get an error:

1114 font_parts.append(f'{weight}')
KeyError: 600
I think this is because maybe a default is making this label bold (600)?
Also tried setting label_props=dict(fontweight=400) or label_props=dict(fontweight='regular') with same effect.
Saving as PDF works, but can't be opened by Inkscape for example.
Might be only Linux-specific.
