Jak zrobić skrypt do wyboru koloru w formularzu?

Jeśli chcesz zrobić np. jakiś internetowy program graficzny to warto w nim dać mozliwość wyboru koloru.
Jak to zrobić - najlepiej mieszając PHP i JS - takie rozwiązanie uprości nam całą konstrukcję. Kolorów jest b. dużo więc warto się zająć zrobieniem w PHP generatora kolorów aby za każdym razem nie budować wszystkiego w html-u
Oto gotowy kod:
