I know I still haven’t pushed out a release in like a month, but just an FYI, there should hopefully be a beta out sometime soon-ish (hoping within the week). There were many areas that were re-written and such. The aim was to allow more flexible input and output, more configurability, and improve color scanning behavior.

Currently, all this work is on the feature/next branch info here #159. We have a new color library that ColorHelper uses and can handle not just sRGB, HSL, HWB, but it can handle LCH, LAB, and others.

Because of this, we’ve reworked color previews as now we have to handle colors that are out of gamut, so some simple gamut mapping is now available or the option to not show the color at all. We’ve added some new color tools as well. Anyways, a lot of work went into this next release which is why the holdup.
