    window.TINY_TERRAIN.colorFunctions.set('linear', (y, colorPalette, paletteRangeMin, paletteRangeMax, paletteAccuracy, colorCache) => {
        const i = ((y - paletteRangeMin)/(paletteRangeMax-paletteRangeMin)).toFixed(paletteAccuracy);
        if (!colorCache.has(i)) {
            colorCache.set(i, colorPalette(i));
