Get color cast using PHP

Question

I want to get a brighter hexadecimal selection of shades from a given hexadecimal value using PHP. For example, I enter the color #cc6699 as input, and I want #ee88aa as the output color. How will I do this in PHP?

Answer 1

You need to convert the color to RGB, make 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;

1. divide the color into three elements: cc, 66, 99 2. Convert it to decimal from http://php.net/manual/de/function.hexdec.php 3. Increment three decimal values ​​4. Convert the decimal to sixth . 5. Put the three elements together

Answer 4

The best solution is to convert RGB to HSL or HSV (just search google for php converter hsl / hsv ).

You can then play with the “lightness” or “value” values ​​of the color space.

Then convert it back to RGB color space.
