Wrong hex color values

[Matheus]

Steps to Reproduce

1. Create a Color object instance (for example green #00ff00)
2. Apply any of the following methods: saturate, desaturate, darken, lighten
3. Call toHex

        const color = Color.Green;
        console.log('Original color:\t',color.toHex());
        console.log('saturate:\t', color.clone().saturate().toHex());
        console.log('desaturate:\t', color.clone().desaturate().toHex());
        console.log('darken:\t\t', color.clone().darken().toHex());
        console.log('lighten:\t', color.clone().lighten().toHex());

Expected Result

It should print a valid hexadecimal representation of a color;

Actual Result

Original color:	 #00ff00
saturate:	 #-c.c0000000000310b.c-c.c00000000003
desaturate:	 #c.c00000000003f2.4c.c00000000003
darken:		 #00e5.800
lighten:	 #19.800000000006ff19.800000000006
