Replace Color with ColorRepresentation

[puxiao]

Box3Helper.js

class Box3Helper extends LineSegments {
    constructor( box, color = 0xffff00 ) { ... }
}

But ...

new Box3Helper(box3, 0xffff00)

//Error: Argument of type 'number' is not assignable to parameter of type 'Color'.

Color.js

set( r, g, b) {
    if ( g === undefined && b === undefined ) {
        const value = r;
        if ( value && value.isColor ) { 
        } else if ( typeof value === 'number' ) {
        } else if ( typeof value === 'string' ) {
        }
    }
    ...
 }

AxesHelper.js

setColors( xAxisColor, yAxisColor, zAxisColor ) {
    const color = new Color();
    color.set( xAxisColor );
    ...
}

So...

AxesHelper.d.ts

- setColors(xAxisColor: Color ...)
+ setColors(xAxisColor: ColorRepresentation ...)
