// create Color from hex

var hexShort = fromCssColor('#fba'); // Color(0xFFFFBBAA)
var hexAlpha = fromCssColor('#fbafbafa'); // Color(0xFAFBAFBA)
var hexAlphaShort = fromCssColor('#fbaa'); // Color(0xAAFFBBAA)

// or from rgb
var rgb = fromCssColor('rgb(100, 5, 32)'); // Color(0xFF640520)
var rgbWithPercents = fromCssColor('rgb(110%, 0%, 0%)'); //Color(0xFFFF0000)
var rgba = fromCssColor('rgb(110%, 0%, 0%, 0.5)'); //Color(0x7FFF0000)

// or from hsl
var hsl = fromCssColor('hsl(100,50%,10%)'); // Color(0xFF15260C)
var hsla = fromCssColor('hsla(-120,100%,50%, .5)'); // Color(0x7F0000FF)

// and a list of X11 keywords is supported
var navy = fromCssColor('navy'); // Color(0xFF000080)
var violet = fromCssColor('violet'); // Color(0xFFEE82EE)
var transparent = fromCssColor('transparent'); // Color(0x00000000)

// convert Color to CSS string
var hexCss = Color(0xFFFBAFBA).toCssString(); // '#fbafba'
