Derive a light-mode palette
Transform every named dark token with one perceptual formula while keeping its key aligned.

background #dedfe2

accent #00139dKeep the roles aligned across both themes
The returned named palette preserves background, text, and accent in the same order while transforming their perceptual lightness and chroma.
Transform the complete named palette
LightModeColorPaletteTransformer returns new color objects and coerces every palette key to a string.
<?php
use PhpColor\Color\Palette\ColorPalette;
use PhpColor\Color\Palette\Transformer\LightModeColorPaletteTransformer;
$dark = ColorPalette::parse([
'background' => '#0b0c0e',
'text' => '#c0cde7',
'accent' => '#4f88fc',
]);
$light = (new LightModeColorPaletteTransformer())->transform($dark);
foreach ($light->toHex() as $name => $hex) {
printf("%s %s\n", $name, $hex);
}
// background #dedfe2
// text #131c2e
// accent #00139dReview the result as an interface theme
The transformer applies an algorithm to colors. It does not understand token semantics or verify the contrast of the resulting role pairs.
LightnessDark values move toward a light background range; light values move toward dark text.
ChromaChromatic colors receive the configured chroma boost.
NamesRole keys and their order remain aligned.
VerificationCheck serialized foreground and background pairs before shipping the theme.
