This isn't too complicated to use is it?

Not in my opinion. I think the target audience is obviously digital artists, who are already used to working with complex graphics programs and this is another great tool to help them design, I know it would have shaved some time for me a year ago when I was working on my own theme and having to use a simple yad color selection utility to do things.

If you open the design window (checkbox), you'll see quite a few more swatches on the right hand side that also drag to the browser to change colors.  The gradient swatch at the top is also draggable like that and if you check the reverse checkbox on the gradient page the swatch will also flip direction.  The left hand column pulls from the style of the loaded webpage and the right hand column pulls from the program and both have some algorithmic swatches added in below those initial colors.

Also, if you click a label under the swatch on the right hand column, you can edit it.  If you click the label under the swatch on the harmony tab, the value copies to the clipboard.  The clipboard is also primary and clipboard simultaneously.  I tried to address as many use cases as I could think of but I may have missed things.

This isn't too complicated to use is it?  I'm open for UI design ideas if it's not a workflow fit for some people.  I based this on what I would consider a good workflow for design but it might not be everyone's cup of tea.

I love the big main pane, so much easier to visualize how the color looks in bigger spaces Also, the ability to click-n-hold the swatches and drag them around to various areas of the screen is just too cool, you can take them to areas in various windows where you may be thinking about changing a color and get an idea of how it will look before you decide to apply them or not. I used the .deb package to install, went perfectly. I do wish there was a daedalus version for us holdouts though, lol, but Gamut needs a newer version of libc6 than daedalus has. All in all great work!

I just compiled this, and I really like the built-in magnification as I have been previously using color-picker alongside magnus. Is there any option to display hex codes in realtime while picking colors the way color-picker does?

Thanks for the feature request.  I added that to xtk_zoom and PixelPrism now has it as well.  I have no idea why I didn't think of doing this sooner.

I've updated everything to use git.devuan.org.

Gamut

PixelPrism

Xtk

I hadn't thought about adding that to the main zoom window but I've now added the feature as it's a reasonable feature request.   I also added a checkbox to toggle it on or off.  I also updated the help files and documentation with the complete keyboard shortcuts.

Would this be more convenient for Devuan devs and users if I migrated to git.devuan.org?  I didn't realize we had a public git repository and would probably have used that initially.

I think maybe so, it's worked great for me, it's another great feature of Devuan that they offer this.

PixelPrism is just a simple color picker tool that uses Xtk and only outputs HSV, HSL, linear RGB, RGB, and Hex.

Xtk will compile as a library to link against or with minor tweaks can be used statically.

I'm extremely pleased that everyone thinks that these are useful.  I use both programs all the time but I'm most proud of Gamut because of the integrated compositor and browser features.  They're both extremely useful for design work and I've tried to make both with as many useful features that I could think of.

I'm glad this is gaining a little traction because it's been a project I've spent years developing.

And it shows, this is incredible work, i've been thinking for a long time about making an "artist" version of my project distro, not another audio/video production spin, plenty of those out there, but instead a raster/vector/photography/fractal/theming type of spin, and I think Gamut might be a perfect advanced-tool addition to such.
