JSCE

Javascript Color Engine

Generate and manipulate colors in Javascript with Objects!

Install

npm i jsce

const { colorEngine } = require("jsce")

Making a color

Instantiate a color with HEX or RGB

const color = colorEngine.createColor("#EEAAAE");
const otherColor = colorEngine.createColor(200,120,20,255);

Using a color

Created colors can be read as HEX, HSLA or RGBA (preformatted for CSS)

someElement.style.backgroundColor = color.hsla // hsla(356,66.7%,80%,1.00)
someElement.style.color =  color.rgba // rgba(238,170,174,255)

Manipulating a color

// Generate 3 analogous colors by manipulating the Hue (.h) of any color
const color = colorEngine.createColor("#AAAAEE");
const color1 = color.hex;
color.h +=15;
const color2 = color.hex;
color.h +=15;
const color3 = color.hex;

//Generate monochromatic shades with ease (great for gradients and shadows)
const color = colorEngine.createColor("#7E7CAE");
const colorShade0 = color.hex;
const colorShade1 = color.monochromatic; 
//18% darker than color if color's lightness as defined by HSLA is >50, otherwise 18% lighter
const colorShade2 = color.monochromatic; 
//36% darker or lighter than color depending on the same criteria. color is not affected.

// .monochromatic will continue adding or subtracting lightness until you reach black or white.
// Changing any value of color
// will reset this count back to the original 18%. This can be overwritten manually
// with color.monochromaticCounter = 1

// Generate the complementary color
const compColor = color.complement;

//Pick a white or black contrasting color for Text depending on the apparent brightness of this color.
const textColor = color.text;
