Cant get it working

[saltnpixels]

Im a front end dev here...

I cant seem to get this working at all. I just wanted to change a hex value to hsl and I'm going down a rabbit hole.

$color = new Color($stripe_color);

Why wont this work? It needs to be a string right?

@saltnpixels:
First, you have to create a new Color object:

$myBlue = new Color("#336699");

The phpColors library has parsed the input value, which is a hex string, and stored it inside the color object. From this internal color representation you can now convert to a color format of your choice, here HSL:

print_r( $myBlue->getHsl() );

Notice the print_r, this is because getHsl() returns a PHP array. You can now pass that array or its individual values to another function/library that expects a HSL color, or output it, render it to a file, etc.

A hex string is just a representation of color, in this case RGB color values. How the computer/library stores and handles it internally, e.g. in what memory address, endianness, etc, should not be a concern here. This library should also work with hex strings that lack the # prefix btw.

... yes I understand this, but I didn’t pass a hex string. I passed a variable holding a hex string called $stripe_color.

It did work whe I passed a random hex string but for us I guess that’s not very useful... the color is coming from the database and has been stored in a variable.

@saltnpixels: You have to inspect the contents of that variable, either using a PHP debugger (which we all use far rarer than we should) or by using a PHP method:

var_dump($stripe_color);

Is the variable content actually a string? Are there any whitespaces (which could arguably be trimmed by this color library), encoding issues?

It’s a hex string and it has no spaces. The return value is #252525.

@saltnpixels: The RGB values for that particular hex string "#252525" are "37, 37, 37", correct?

....I have no idea. That’s why I’m using the plugin 😬

My goal is to take in a hex and check if the color is light or dark.

Use the isLight or isDark methods, they accept a hex string as input.
