libpercentualcolor

Sponsor: Albert Astals Cid

This library provides various Qt GUI components for choosing colors, with focus on an intuitive and perceptually uniform presentation. The GUI widgets are based internally on the LCH color model, which does reflect the human perception much better than RGB or its transforms like HSV. However, the widgets do not require the user itself to know anything about LCH at all, because the graphical representations is intuitive enough.

Manifesto Compliance Plan

List the actions planned to get in compliance with the manifesto.

Values

Open Governance

Open Governance will happen through discussions in invent.kde.org issues

Free Software

Compliance with KDE’s licensing policy by publishing under a permissive license.

Inclusivity

Anyone is welcome to make Merge Requests.

Innovation

The project provides a color picker that displays a perceptually uniform color space to choose the color. This is more intuitive than the current color pickers, who’s diagrams are not perceptually.

Common Ownership

The Git repository will move to invent.kde.org

End-User Focus

The project will focus to deliver an intuitive color dialog that “just works”, with a library API that is rather small and – to the degree it’s possible – source-code compatible with QColorDialog.
