There are a number of ways of doing this, from manipulating the RGB channels using a GPUImageRGBFilter, applying a color matrix to it using a GPUImageColorMatrixFilter, adjusting the hue using a GPUImageHueFilter, making a lookup table using GPUImageLookupFilter, or adjusting the white balance using GPUImageWhiteBalanceFilter. As you can see, there are many ways to skin that cat.
I have an image which I want to give a "Yellow-ish" shade to.
How can that be achieved?
