Created attachment 150087 [details] pic SUMMARY I made a hypothetical design for “color balance”：https://krita-artists.org/t/i-dont-see-the-point-of-this-change/40531/27 First, a gradient of the modification range is displayed above（after “shadow”“midtones”“hightones”）. （0-117） （53-202） （138-255） When “preserve luminosity” is turned on, “shadow” is darker as a whole and “highlight” is brighter as a whole For turning off preserve luminosity, the brightness of the three is the same, but the color on the left is slightly darker and the color on the right is slightly brighter. This design does not affect the trend of color change, and increases the hint of light and dark
