Nonlinear color triads for approximation, learning and direct manipulation of color distributions
ACM Transactions on Graphics (TOG), Volume 39, Issue 4Article No.: 97, Pages 97:1–97:13https://doi.org/10.1145/3386569.3392461We present nonlinear color triads, an extension of color gradients able to approximate a variety of natural color distributions that have no standard interactive representation. We derive a method to fit this compact parametric representation to existing ...
