The "Luminance Adjustment" option in PixMaster is a powerful tool for controlling the brightness or darkness of specific colors in your image. Here’s how it works:

1. Increasing Luminance: When you increase the luminance of a color (for example, blue), it makes that color brighter in the image. This means areas that are predominantly blue will appear lighter.

2. Decreasing Luminance: Conversely, decreasing the luminance of a color darkens that specific color in the image. This adjustment is useful for making colors appear deeper or more muted.
