RGB black can't be added to palette

[biologeek]

Hi !

While testing the RGB mode, I created a custom palette containing (among others) black color.

When generating the component, in the verifyPalette(palette) function, verification fails due to these lines :

if (!color.hex && !color.r && !color.g && !color.b) {
                throw Error('Colors must provide at least a hex or rgb value');
}

As color is defined with its R, G and B attributes that are all 0, color.r, color.g, color.b and color.hex are all falsy values.

Could you please check this issue ?
Thanks for your work on this nice component !

This could solve the issue :

if (!(color.hasOwnProperty('hex')
                || (color.hasOwnProperty('r') && color.hasOwnProperty('b') && color.hasOwnProperty('g'))
                )) {
                throw Error('Colors must provide at least a hex or rgb value');
}
