HLC Atlas Metamerism Analysis is a WordPress plugin designed for the fast and intuitive evaluation of metamerism effects within defined HLC Atlas color pairs. It helps users compare color similarities and potential deviations under specified conditions in a structured and transparent way.
The plugin is particularly suitable for applications in design, product development, surface planning, color communication, and lighting assessment. With its integrated database, color pairs can be selected, analyzed, and visualized directly within the WordPress environment. Integration is straightforward via shortcode, making the tool easy to embed into existing websites, internal workspaces, or project portals.
Key benefits:
- easy integration via shortcode
- browser-based analysis without external services
- structured visualization of defined HLC Atlas color pairs
- suitable for preliminary assessment, documentation, and visual comparison
- ideal for agencies, planners, designers, and technical teams
Note: This plugin is intended as a digital analysis and comparison tool. It supports the evaluation of color constellations at an early stage, but it does not replace real-world material or lighting tests under practical conditions.
Metamerism Analysis (Atlas-based)
Compare two valid atlas references using measured spectra-derived structural attributes. This module does not create colors and does not alter atlas identity.
Method
- Identity: valid atlas reference in the form
Hxxx_Lxxx_Cxxx. - λ*_V2: Brent-based energetic balance point.
- λ*_EE: reflectance-weighted centroid.
- Δλ*: primary structural asymmetry indicator.
- μ₂, σ*, μ₃, γ₁: structural spread and asymmetry descriptors.
- Ambient upload: preview only. It does not create a new atlas color or change atlas identity.
