CMYK Colour and RGB Colour Mein Fark kya hai & Full Definition

CMYK Color Model aur RGB Color Model dono different color models hain, lekin inka use alag situations mein hota hai. In dono ka main difference color creation aur application mein hai.
CMYK is a subtractive color model used in printing processes, such as offset printing, screen printing, and inkjet printing. The CMYK model combines different amounts of cyan, magenta, yellow, and black inks to produce a wide range of colors.
- C (Cyan): 0-100%
- M (Magenta): 0-100%
- Y (Yellow): 0-100%
- K (Key/Black): 0-100%
For example, to create a deep blue color in CMYK, you might use:
- C: 80%
- M: 50%
- Y: 0%
- K: 20%
1. CMYK (Cyan, Magenta, Yellow, Key/Black) Color Model
CMYK model ka use printing ke liye hota hai. Ismein 4 primary colors hote hain:
- Cyan (C)
- Magenta (M)
- Yellow (Y)
- Key/Black (K) (Yeh black hota hai, aur ‘Key’ ka matlab “key plate” hota hai, jo printing process mein main layer hota hai.)
CMYK subtractive color model hai, jo yeh assume karta hai ke jab colors ek dusre par add hote hain, to light absorb hoti hai. Isliye, jab aap cyan, magenta, aur yellow inks ko mix karte hain, to aapke paas puri range of colors generate hoti hai. Yahan black (K) ka addition usi liye hota hai, kyunki inks ke combinations se perfect black produce karna mushkil hota hai.
Key Points:
- CMYK ka use printing (physical mediums) mein hota hai.
- Colors ko subtract karte hain, yani jahan aap colors ko mix karte hain, wahan light absorb hoti hai.
- Print media mein use hota hai, jaise magazines, brochures, etc.
2. RGB (Red, Green, Blue) Color Model
RGB model ka use digital screens (monitors, TVs, mobile phones, etc.) par hota hai. Ismein 3 primary colors hoti hain:
RGB is an additive color model used in digital displays, such as monitors, televisions, and mobile devices. The RGB model combines different intensities of red, green, and blue light to produce a wide range of colors.
- Red (R)
- Green (G)
- Blue (B)
- R (Red): 0-255
- G (Green): 0-255
- B (Blue): 0-255
For example, to create a deep blue color in RGB, you might use:
- R: 0
- G: 50
- B: 150
RGB additive color model hai, jo yeh assume karta hai ke jab different lights ko mix kiya jata hai, to colors generate hote hain. Yani, jitni zyada light combine ki jaati hai, utni brighter aur white light milti hai. RGB mein, jab aap red, green, aur blue colors ko mix karte hain, to aapko white light milti hai.
Key Points:
- RGB ka use digital screens (electronic media) mein hota hai.
- Colors ko add karte hain, yani jab light combine hoti hai to brighter colors aur white light ban jaati hai.
- Screen-based media mein use hota hai, jaise computers, smartphones, etc.
Difference Between CMYK and RGB
- Color Mixing:
- CMYK: Subtractive (colors subtract light).
- RGB: Additive (colors add light).
- Use Case:
- CMYK: Printing (physical media).
- RGB: Digital screens (electronic media).
- Color Creation:
- CMYK: Primary colors are Cyan, Magenta, Yellow, and Key (Black).
- RGB: Primary colors are Red, Green, and Blue.
- Color Behavior:
- CMYK: More effective for achieving dark or muted colors (since inks subtract light).
- RGB: More effective for bright, vibrant colors (since screens add light).
Summary:
- CMYK is for printing and uses subtractive colors, while RGB is for screens and uses additive colors.

What is CMYK Color?
CMYK stands for Cyan, Magenta, Yellow, and Key (Black). It is a subtractive color model used primarily in color printing. In this model, colors are created by subtracting different percentages of light, which is why it works well for print media.
- Cyan (C): A blue-green color.
- Magenta (M): A pinkish-red color.
- Yellow (Y): A bright yellow color.
- Key (Black) (K): Black ink used to enhance depth and detail, and also to produce darker colors.
In the subtractive process, colors start as white (reflecting all light), and inks are added to subtract portions of light to create a color. For example, mixing cyan and yellow produces green because it subtracts red from the light. When all the colors (C, M, Y) are mixed, it creates black (but because of printing limitations, true black isn’t achieved with these three, so black ink is added separately).
Why is CMYK Used?
CMYK is primarily used in printing because printers use ink, and the subtractive color process is perfect for that. The model helps to create full-color images by mixing the primary inks (cyan, magenta, yellow) in various proportions. The black ink is added to make the printout richer and more detailed, especially in darker areas.
Used in:
- Magazines
- Brochures
- Posters
- Business cards
- Other print materials
What is RGB Color?
RGB stands for Red, Green, and Blue. It is an additive color model used primarily for digital screens (such as monitors, TVs, and phone displays).
- Red (R): A primary color.
- Green (G): A primary color.
- Blue (B): A primary color.
In the additive process, colors are created by adding different intensities of red, green, and blue light. When combined, these three colors can produce millions of different colors. When all three colors (Red, Green, Blue) are mixed at full intensity, they produce white light. The more you add each color, the lighter and brighter the color becomes.
Why is RGB Used?
RGB is used for digital screens because screens emit light. The additive process of combining light (instead of absorbing it like in printing) is ideal for devices like computers, TVs, and phones. The RGB model allows screens to display vibrant, bright colors because adding more light creates brighter and more vivid colors.
Used in:
- Computer monitors
- Televisions
- Mobile phones
- Digital displays
- Websites and digital design
