Setting custom colors

[robinsonkwame]

The default gray for ABSTAIN labels is difficult to see on my screen. I wondered if there was an easy way to set custom color per label.

On the recipe​ (i.e. simple_annotator​) level there currently isn’t. For ABSTAIN the light gray color is kind of the point — ABSTAIN is the unlabeled background upon which labeled colors are applied.

If you’d like a custom color palette, the best place to do it is probably a Recipe​ class. Let me give more thought to this.

Best regards, Haochuan

Great, looking forward to it. I actually thought the Bokeh icon was a color wheel and clicked it to modify the current label color.

As an aside, maybe a roadmap needs-help-issue, UI accessibility will be greatly enhanced if users are able to control color settings and defaults. For example, Bokeh put accessibility related concerns on their roadmap, https://github.com/bokeh/bokeh/issues/12259, and other products let you specify color settings, such as the commercial prodi.gy that has a crude bulk labeling script. Libraries like colorcet provide ready made perceptually accurate pallets for dense data visualizations (colorcet.holoviz.org) too.
