Move through thickness to see colour emerge from distance.
Thin-Film Interference
The colour of a soap bubble, a beetle’s back, and oil on a puddle is not pigment — it is interference. Two reflections meet out of step by 4π·n·d·cosθ/λ, and what survives is integrated here at 24 wavelengths. Drag the thickness and watch the fringes climb Newton’s series.
Colour, measured in distance.
Read across the wedge from 60 to 900 nm. The marker follows your film thickness; the angle controls this flat-surface comparison. The colour preview uses the selected material’s display exposure (6.5×); the spectral curve shows unamplified reflectance.
Illustrative two-interface interference model. The angle is measured inside the film; the curve shows reflectance before display exposure.
A little interference at the edge.
Use the sampled colour as a fine rule or small accent while keeping the reading ground steady.

Pin a plate before changing the controls. Each pin keeps its own recipe and lighting context.
Carry this specimen into another tool
The image travels locally in this tab with its source recipe. This is a flattened plate: the destination does not recreate fluid motion or convert material coefficients.
