Get Color Shade with PHP

Question

I want to get brighter hex colour shade output from a given hex value with PHP. For example, I give the colour #cc6699 as input, and I want #ee88aa as the output colour. How would I go about doing this in PHP?

Answer 1

You need to convert the color to RGB, make the additions, and convert back:

// Convert string to 3 decimal values (0-255)
$rgb = array_map('hexdec', str_split("cc6699", 2));

// Modify color
$rgb[0] += 34;
$rgb[1] += 34;
$rgb[2] += 17;

// Convert back
$result = implode('', array_map('dechex', $rgb));

echo $result;
