Free TouchDesigner Component: OKLCh Color Space Picker, Adjust and Feedback Edge (offlineartisan)

Overview

offlineartisan shares a set of toxes in the Derivative community Asset section that make it easy to use the OKLCh color space in TouchDesigner. OKLCh is based on the OKLAB perceptual color space, with lightness, chroma capped around 0.3 for sRGB displays, and hue expressed in radians for GLSL trig functions.

LChPicker is a simple LCh color picker, LChAdjust covers common options of the HSV Adjust TOP and can clamp lightness and chroma for feedback loops, and LChFeedbackEdge is the palette's FeedbackEdge with LCh adjustment. LCh_Picker.tox, LCh_Adjust.tox and feedbackEdgeLCh.tox are free direct downloads from the post.
