M: magenta = magenta, also known as "magenta";

Y: yellow = yellow;

What color is navy blue, and what is the proportion of each color?

In this tutorial, we carefully explain the principles of these PS color matching tools and deepen your understanding with examples. First, hue/saturation In an environment where you are not familiar with color, we have been exposed to this color finishing method. It is mainly used to adjust the tone of an image. It is similar to turning red into blue, turning green into purple and so on. At this time, let's prepare and familiarize ourselves with this adjustment method. Let's take pictures with the flowers below. Image hue/saturation adjustment "[〖CTRL U〗] opens the setting box. Once we know that the hue can be adjusted by dragging the hue slider, we should pay attention to the following two chromatograms of hue (chromatographic knowledge is in the course #0 1), in which the following chromatograms remain unchanged and will be adjusted with the dragging of the hue slider. The forms of these two chromatograms are actually telling us the results of tone adjustment. See the figure below. Check the changing environment of hue chromatogram in the two boxes. Before adjustment, red corresponds to red and green corresponds to green. After adjustment, red corresponds to green and green corresponds to blue. This is to inform us of the adjustment effect suitable for the color gamut in the image. See the figure below. The red flowers in the picture become only green, and the green leaves become only blue. Saturation is the deep water level that controls the color of the image, similar to the color difference in our TV set. Meanwhile, the chromatogram below will be adjusted. At the lowest moment, the image becomes a gray image. It has no effect on adjusting the tone of gray image. Brightness is brightness, similar to the brightness level of TV. If you turn the brightness to the lowest, you will get black, and if you turn it to the highest, you will get red. It has no effect on the overall hue or saturation of black and red. Be careful of the effect: you can start the experiment by private letter, so you won't put the picture here. There is a "color" option in the lower right corner of the setting box, which is used to change the picture to the same color effect. There are many half-yard wedding photography that often use this effect. It's as simple as clicking the "Color" option and then dragging the hue to adjust the color. As shown on the left. "Coloring" is an operation that "monochrome replaces black" and retains the original pixel brightness. Change the red, yellow, purple and other colors with different shades in the original picture into multiple colors with different shades. Note that the color spectrum below becomes only brown, which means that brown replaces the full color tone at this moment, so the whole image should be brown at this moment. Drag the slider bar with more tones to select different monochromatic colors. The other three pictures below. You can also adjust saturation and lightness at the same time.
