There was a bug when converting rgb(0,0,0) to Cmyk
$rgb = (new Rgb(0,0,0))->toCmyk();
PHP Error: Division by zero in .../vendor/spatie/color/src/Convert.php on line 67
This error occurs when
$keyNeg
will be 0.Another bug is when converting i.e. rgb(27,12,98) to Cmyk.
$rgb = (new Rgb(27,12,98))->toCmyk();
Spatie\Color\Exceptions\InvalidColorValue with message 'Cmyk value
yellowmust be a number between 0 and 1'
I fixed both bugs and added tests.
