How to tune Klein Blue?

Open the rough sketch to import the original image, reduce the contrast, improve the black color, make the picture brighter, and avoid color overflow during curve adjustment. HSL adjusts the green and cyan in the picture to reduce its saturation and adjust it to the right at the same time to avoid the two colors interfering with the purity of blue when the curve is adjusted! Curve adjustment, RGB curve compresses black part and white part, making the whole picture quiet and light.

Adjust the middle and highlighted parts locally at the same time. Press the red right end point, and the left end point will shift to the right (the picture is blue at this time). When the right end of the green curve is pressed, the picture will begin to appear blue, and some purple in the dark will be adjusted, but the whole is not blue enough. The right end will be shifted to the left, and the left end will be raised, and the picture will reach the color we want!

The overall saturation of blue is a bit high. HSL desaturates the blue color, click the brush icon on the right to enter the mask-select the lightness mask-the following options are the first to drop down the left black-feathering 30- adjust the following to make the dark part more stereoscopic! Finally, we cut it according to the ratio of 1: 1 and cut it into squares, and our effect will be adjusted!
