Apply one hue offset to every color instead of rebuilding each token separately:

use PhpColor\Color\Palette\ColorPalette;

$source = ColorPalette::parse([
    'primary' => '#7c3aed',
    'secondary' => '#0ea5e9',
    'accent' => '#f59e0b',
]);

$shifted = $source->rotateHue(24);

assert([
    'primary' => '#a51dca',
    'secondary' => '#6498f4',
    'accent' => '#d6b000',
] === $shifted->toHex());

rotateHue() returns a new palette and leaves $source unchanged. It preserves the relative hue offsets, not the semantic suitability or contrast of each token.

See palette transformation or ColorPalette.
