Batch converting layers to Color Type


Is there a way to batch convert existing layers to Color layers? I do not want to change the master color.

For example: I change the glyph A from “Regular” layer type to “Regular Color”. But when I select more than one glyph (A, B, C, D) and do the same, it doesn’t change.

Do I have to individually change the layers of each glyph?

Thank you.

Best through scripting.

Can you help me with that or guide me to a resource? @mekkablue

You want to turn them into SVG glyphs?
