We are trying to use the hue filter on a uniform color image in order to add some color customization to our game. We have used photoshop to find wanted hue values for the image. The problem is that there seems to be a slight problem with the colors when they are in the app. It looks like some of the colors are darker than we expect them to be when finding the values in photoshop. We can reproduce this effect in photoshop by also turning the lightness of the image down when adjusting the hue.
We also noticed that the corona hue filter will change the color of white in images while the photoshop hue filter does not tune the color of black or white in images. Though we solved this by using the hue filter on a uniform color image.
Does anyone have an explanation for this or have experienced something similar? Is this even a good way of doing this? Is this a known issue that different programs have differently behaving hue functions?
EDIT: The corona hue filter changes the color of the white in an image, not that black as I first stated.
