Essentially when the contrast is increased, the pixel's \(L\) value gets "pushed away" from the center of the values' scale, and when the contrast is decreased the \(L\) is being "pushed towards" the center. | Essentially when the contrast is increased, the pixel's \(L\) value gets "pushed away" from the center of the values' scale, and when the contrast is decreased the \(L\) is being "pushed towards" the center. |

| ===== In RGB color space ===== |

| ===== In HSL color space ===== |
For our purposes we are going to adjust the pixel's \(L\) component in the HSL color space, leaving the other two components intact as the Saturation shouldn't be affected by the Contrast and the Hue (at least for now) is also maintaining its invariance during this operation. | For our purposes we are going to adjust the pixel's \(L\) component in the HSL color space, leaving the other two components intact as the Saturation shouldn't be affected by the Contrast and the Hue (at least for now) is also maintaining its invariance during this operation. |
