So, I have a rather strange problem with Imagick in my application. The app uses a higher input to create the "pet" that they choose for color, breed, etc. After the pet is generated, its hexadecimal values are stored in the database, and then they can later supply items to the pet. A demo for this functionality is here.
The problem I encountered is the second script, which updates and re-saves the pet when the user equips it and the item to it, or if the pet grows from a child to an adult. When I run this script, the animals suddenly appear much darker than they were created, as shown below:
, , . , COMPOSITE_MULTIPLY
COMPOSITE_OVERLAY
