Perceptual color tools for Unity.
Design, compare, and validate color transitions using OKLab instead of RGB to avoid muddy gradients, hue drift, and accessibility issues in UI and theme systems.DAWG Tools - OKLab Color Inspector PRO - Perceptual Color Tools for UnityUnity’s default Color.Lerp interpolates colors in RGB component space.https://dawgtools.org/unity/For UI and theme transitions, this often results in:Desaturated or “dirty” midpointsPerceived brightness dipsUnintended hue shiftsInconsistent animation qualityThe OKLab color space is designed so that distance and interpolation better match human perception.This tool makes the difference visible, measurable, and actionable inside the Unity Editor.OKLab interpolation produces smoother, visually consistent gradients and transitions because it operates in a perceptual color space rather than raw RGB component space.Instead of guessing how a transition will look, you can:Compare Gamma RGB vs Linear RGB vs OKLab interpolationInspect perceptual midpointsMeasure ΔE distance between colorsValidate contrast compliance before shipping1. Typical WorkflowSelect two UI colors (e.g., Normal → Hover).Compare Unity RGB interpolation against OKLab interpolation.Inspect midpoint, hue drift, chroma, and contrast.Replace Color.Lerp with OKLabColor.Lerp in runtime code.2. Who It’s For:UI / UX engineersTechnical artistsTools programmersTeams implementing dynamic themesDevelopers who care about visual polish and accessibility3.
