How to turn a hash into a random color.. Notice that I used the expression "hash" only to say that a cluster of letters/numbers can be transformed into colors, like this:

d0be2dc421be4fcd0172e5afceea3970e2f3d940

is meaningless, meaningless but whenever this hash is used it will give a specific color and if the end is changed 0 for 1 will show another color.. or even if any part of the hash is changed it will show different colors.

Note: I think there are infinite ways to mount a hash but I’m not sure if there are infinite colors so it’s okay if different hashs give an equal color (even if it’s not ideal)

Can you understand? , the color format I would like it to be RGB but can be in style #FFFFFF I don’t make a distinction, I thought of something like this: Take three parts of the hash one at the beginning another in the middle other at the end and work from it to pick up colors, but as I don’t know how to generate these colors after picking up these parts I come to ask help..

php colors

  • You can do in array and mount a reading function as the hash passed... If hash x returns color x but returns color y

  • You’ll store these hashs and colors somewhere?

By directly answering the question the way to turn a hash into a color will be:

function hashToColor($hash) {
  $code = dechex(crc32($hash));
  $code = substr($code, 0, 6);
  return $code;
}

Obviously the example can be optimized but this is the solution I give you. Simple and direct for easy understanding.

However, the use of CRC32 logo of origin obviously taking into account the possibility of collisions etc.

Since there is no relationship between your hash and the color it will represent, this process is totally random.

You didn’t specify like this hash this being generated then I will show only how you can generate the value for colors in the format hexadecimal

echo sprintf("#%06x",rand(0,16777215));

This code will generate values such as: #7bdc39.

Now you can associate each new hash with this command.
