Color font problem

I have developed apps that use a custom color font. The fonts have worked fine for the last year, but a new app I’m developing has a font problem. The artwork for the color font looks fine in Glyphs, but the TTF font distorts the color. The did not happen with previous fonts. Here’s an example:


Can you send me the .glyphs file and the exported .otf?

Did you receive my files? Any ideas why the ttf color font displays the colors different from the artwork? Looks fine in Glyphs.

I don’t think so.

Zip file resent to your email.

What version of macOS do you have? When I export under 10.13, it looks good.

I’m running High Sierra 10.13.4. I exported again and still same problem. I looked at the font using Font Book to ensure it is not my app causing the problem and the colors are still off. The gold string turns to yellow. It looks fine in Glyphs before I export. Here’s the original app with font and new app with new font.

I installed Glyphs 2.5.1 and that fixed the problem.

This may also be fontcaching problem. Have you read this tutorial:
