bright2Opacity	Generate brightness with respective transparency.	(brightness: number, option: { min: number; max: number } = { min: 0.2, max: 1 })	None
brightKelvin2rgb	Convert the brightness and color temperature values of white light to red, green, blue, alpha (RGBA) color values.	(bright = 1000,kelvin = 1000,{ temperatureMin = 4000, temperatureMax = 8000 } = {})	None

Example

import { ColorUtils } from '@tuya-rn/tuya-native-lamp-elements/lib/utils';


ColorUtils.brightKelvin2rgba(700, 1000);  //rgba(224, 232, 255, 0.76)

ColorUtils.hsv2rgba(0, 1000,1000);  //rgb(225,0, 0)

ColorUtils.bright2Opacity(700, { min: 0.5 }); //0.85

ColorUtils.brightKelvin2rgb(700, 1000);  //rgb(157, 162, 179)
