sRGB hex colours and linear components.

Members ​

Member Kind Summary
toLinear method Linear Rec.709 components 0..1 of an sRGB hex colour.
toHex method The sRGB hex colour of linear components 0..1.
parse method Checks a string from your data: '#rgb' or '#rrggbb' (any case), returned as '#rrggbb'; null otherwise.

Declaration ​

ts
export const color: {
  toLinear(hex: HexColor): {
    r: number;
    g: number;
    b: number;
  };
  toHex(linear: {
    r: number;
    g: number;
    b: number;
  }): HexColor;
  parse(text: string): HexColor | null;
};

Example ​

Imports: values (has, validate, the Holo*Error classes, the pure helpers) from @holostep-configurators/runtime-client, types from @holostep-configurators/runtime-client/contract, /math and /testing names from those entries; boot from the runtime module the root's loadRuntimeAtFloor resolves to. A type your page defines is your app's: declare it there, never import it from the package.

Compiled under the contract's strict settings (examples/declaration/23-color.ts):

ts
import { color } from '@holostep-configurators/runtime-client/math';
import type { Session } from '@holostep-configurators/runtime-client/contract';
declare const session: Session;
declare const signal: AbortSignal;
declare const row: { colour: string };                    // a string from your data, not a HexColor
const hex = color.parse(row.colour) ?? '#ffffff';
await session.find({ tag: 'frame' }).set({ material: { baseColor: hex } });

Generic-API test (spec 3.1) ​

Rule Result
1. Neutral name pass: color names no product
2. A precedent not recorded: no ledger row (coverage.json) names this member or its owner
3. Two apps, or labs not recorded: no ledger row names this member or its owner
4. The cheaper fix first not recorded per member (Appendix B decides it per need)
