Modul:Bak pasir/Hidayatsrf/SpectralColor/doc

This module generates the 'rgb(r,g,b)' HTML code of the approximate color of a given wavelength.

Usage

exported function :

• Lambdacolor(frame) – returns the "rgb(r,g,b)" code of the wavelength given as first argument

Uses :

• mw.frame – args[1] = longueur d'onde en nanomètres (entier)

Note : The color tables comes from File:Spectrum-sRGB-low.svg. Tables are big and by step of 2 nm, so interpolation is not necessary

Examples

• Spectral lines of mercury 405 nm(ultraviolet), <span style="background-color:">436 nm, <span style="background-color:">546 nm and <span style="background-color:">a doublet near 578 nm
• <span style="background-color:">Triplet of magnesium near 517 nm
• <span style="background-color:">Doublet of sodium near 589 nm
• <span style="background-color:">Spectral line Hα of hydrogen at 656 nm
• {{#invoke:SpectralColor|lambdacolor|589}} gives ''
