resolveIncomingRequested

function resolveIncomingRequested(
  previous: Color,
  incoming: Color,
  options: ResolveIncomingRequestedOptions,
): Color;

When incoming is achromatic (chroma at or below ACHROMATIC_CHROMA_THRESHOLD) and its hue is not explicit (or is not finite), the result keeps previous.h; lightness, chroma and alpha stay as converted. Raising chroma afterwards therefore resumes the previous hue instead of jumping to the canonical achromatic hue 0 that conversions report. Chromatic inputs and explicit hues are returned unchanged (same reference), as is incoming when it already holds previous.h.

Parameters

Returns

Color

Example

import { parse } from '@pbroom/color-kit';
import { resolveIncomingRequested } from '@pbroom/color-kit/driver';

const gray = resolveIncomingRequested(
  { l: 0.6, c: 0.15, h: 250, alpha: 1 },
  parse('#808080'), // h: 0
  { explicitHue: false },
);
gray.h; // → 250
gray.l.toFixed(2); // → '0.60'
