The image adjustment you're referring to is often called Hue/Saturation or Color Range adjustments. These tools allow users to select a specific color range within an image and then modify the hue, saturation, and brightness of that color spectrum.
In software like Adobe Photoshop, for instance, you can use the Hue/Saturation adjustment layer, set it to target a specific color (like reds, greens, etc.), and then adjust the sliders to modify the selected color's appearance throughout the image. Similarly, other image editing software may offer similar features under different names, such as Selective Color or Color Balance.
If you're using a more advanced tool, you might also encounter features like Color Wheels or Curves that provide a more nuanced control over the color adjustments.
