CMYK to RGB is a free online color code converter, which converts a color hue to another color model,and it supports three color models, RGB and HEX, CMYK.

How to convert CMYK(100, 0, 0, 0) to RGB(0, 255, 255)

The Red, Green, Blue values within the range 0-255.the red color(R) is obtain from the cyan(C) and black(K) colors, the green color(G) is obtain from the magenta(M) and black(K) colors, The blue color(B) is obtain from the yellow(Y) and black(K) colors.

CMYK to RGB conversion formula

we can calculate The red (R) color the cyan (C) and black (K) colors
R = 255 × (1-C) × (1-K)
we can calculate The green color (G) from the magenta (M) and black (K) colors
G = 255 × (1-M) × (1-K)
we can calculate The blue color (B) from the yellow (Y) and black (K) colors
B = 255 × (1-Y) × (1-K)

            if (k > 1) k = 1;
                    r = Math.round((1 - c) * (1 - k) * 255);
                    g = Math.round((1 - m) * (1 - k) * 255);
                    b = Math.round((1 - y) * (1 - k) * 255);

How to Correct the color of Photo in Photoshop

Sometimes you need to correct the color in the image. If you know about the Photoshop then you can easily improve the colors of the image and if you do not know about then no matter in this post we will discuss how we will correct color in the image.

Saturation adjustment tips

An increase in saturation can also create noise in the image.
Some types of pictures, especially in Portrait, the increase in Saturation may seem immutable.
In these cases, you can reduce the saturation.The Hue slider replaces all the colors in the image at the same time. This will often result in an unnatural color can use the Lightness slider to increase or decrease the image brightness, you can also add a Level or Curve adjustment layer instead – this will give you more control over image brightness.


An increase in saturation may sometimes appear to be unnatural. Using the Vibrance adjustment layer instead of Hue / Saturation will be correct. Vibrance promotes Saturation for those parts of the image which are already less colorless without overcoming the colored parts.
Converting to black and white Setting Saturation to 100 will create a black and white image. For better results, you can create a black and white adjustment layer

Auto-adjusting tools

Some images may require more special improvements if you do not have much experience with Photoshop,then it may be difficult to create.there are many auto adjusting tools you can use to improve your images.

Color science is an important topic in some industries such as the production of digital printing and printers, photo-furnishing, medical imaging, surveying, astronomy and many other areas of science.
Color is an important part of multimedia. Images can be made attractive and these can be viewed separately from the background. The color or grayscale is also part of our life.
Color science allows you to measure the colors and change them according to the human vision system, which starts with a device characterization step.
Device characterization allows us to understand how a device responds to colors or prepares colors from a signal. Once a device is characterized using all the potential signal ranges then a model can be prepared that manipulate the input signals and transform them into new signals that can give the desired result between input and output and intermediate display devices.
Arrangement of colors or management is called color management.
The color measurement system is called Cliometric, which creates a base from which colors can be manipulated, Mathematics models which fall under the human vision system, define the colors numerically and by bringing the colors from the raw Spectrum map.
