Font Color - Custom Fonts

[findthebug]

Using parseBMP to load custom font which is working as expected. See image below. Now, i try to set the font-color, but i can't this getting working. I think poco is using bitmap images but in the pebble source is just exporting the alpha one? do i miss something?

In my app im using the code from this example:
https://github.com/Moddable-OpenSource/pebble-examples/blob/main/hellopoco-text/src/embeddedjs/main.js

black on white and white on black is working, but as soon as i set a color, its not working. using the pebble native fonts, the color is rendered correct, but not for the custom ones.

Thank you for the report. We fixed a similar issue a little while back. That should be included in the most recent firmware. Please add the version of the Pebble OS firmware and Pebble SDK you are using to this report. Thanks!

Pebble Tool v5.0.35 (active SDK: v4.9.169)

Thank you. colors working now for custom fonts. One small note:

{
"source": "./assets/DiaBold",
"size": 48,
"monochrome": true,
"blocks": ["Basic Latin", "Arrows"]
},

monochrome needs to be true, otherwise font is rendered black (as before). not sure but i would expect the oposit behavior. true = no colors, false = with colors?

Nice. Thanks for checking.

That's a real bug. Here "monochrome" refers to the font data itself - 1-bit fonts. Often that is what you want for Pebble – it looks reasonable and the data is small. The color applied when rendering the font is independent of that. A non-monochrome font is grayscale which means that there is anti-aliasing in the font. Because Pebble has a limited palette of 64 colors, anti-aliasing is minimal and of varying effectiveness depending on the color you use to render the font.

I'm leaving this issue open as a reminder to look into the grayscale font rendering with colors.
