Jens: I can't get Robochrome to open from Extensions. It shows up in the menu, I can get to the help file, but the extension window itself doesn't open up—click the title and nothing happens. I've tried both with one of my UFO files and one of your demos, FF Copa, open. I'm using Mojave and RF 3.3.

It seems with the new FonTools if you make a new Color() object you need to fill the four values and if you want to change one, you can't access it with its name (variable. red).
So color = fontTools.ttLib.tables.C_P_A_L_.Color() doesn't works and color.red = Value neither.

Hi Jens,

I’m having an issue exporting fonts with Robochrome. I downloaded the latest (0.7.3) through Mechanic and I’m running Robofont 3.3 (1911061105) on Mojave (10.14.3).

After adding a color palette (the default black and black again at 50%) and assigning color layers to base glyphs, I exported a standard OTF with Robofont and then tried generating a SVG.

Robochrome stalls at Rendering SVG and I get the traceback:

Exporting SVG format with palette 1 ...

Do you have any clues on fixing this?

Thanks so much.
