What approaches can be used to resolve issues with color blending or transparency in graphics or images?

To fix color blending or transparency issues in graphics or images on iOS, you can use the following approaches:

• Use the correct color space (e.g., sRGB) when loading and displaying images.
• Ensure that the alpha channel (transparency) is handled correctly and not blended improperly with the background.
• Apply blend modes in Core Graphics or Core Animation, such as kCGBlendModeNormal or others suitable for the specific task.
• Use image formats that support transparency, like PNG, instead of formats without alpha, like JPEG.
• When working with CALayer or UIView, set the opaque property to false if transparency is needed.

For example, if an image appears with incorrect transparency, you can check and set:

imageView.layer.isOpaque = false
imageView.backgroundColor = UIColor.clear

This helps display transparent areas correctly without color blending.
