Here is our advanced CMYK to RGB converter that will help you instantly get the RGB values to further utilize it in fields, like web designing, digital photography, graphics, etc.
How to Convert CMYK to RGB
Converting CMYK to RGB is pretty straightforward, with just two steps involved. Here’s a manual calculation of this conversion, including an example.
Normalization of CMYK Values
Divide each CMYK component by 100 to obtain normalized values in the range of 0 to 1:
C* = C / 100
M* = M / 100
Y* = Y / 100
K* = K / 100
Example: Let’s consider the CMYK values:
- Cyan (C) = 30%
- Magenta (M) = 40%
- Yellow (Y) = 20%
- Black (K) = 10%
Interpreting Formula
- C* = 30 / 100 = 0.3
- M* = 40 / 100 = 0.4
- Y* = 20 / 100 = 0.2
- K* = 10 / 100 = 0.1
Conversion to RGB
Calculate RGB values using the following formulas:
R = 255 × (1 – C*) × (1 – K*)
G = 255 × (1 – M*) × (1 – K*)
B = 255 × (1 – Y*) × (1 – K*)
Interpreting Formula
- R = 255 × (1 – 0.3) × (1 – 0.1) = 160.65 ≈ 161
- G = 255 × (1 – 0.4) × (1 – 0.1) = 137.7 ≈ 138
- B = 255 × (1 – 0.2) × (1 – 0.1) = 183.6 ≈ 184
Interpreting RGB Color Code
The resulting RGB color code represents the color in whole numbers, broadly used in electronic displays, such as televisions, computer monitors, and smartphones.
Interpreting Formula
RGB values:
- R = 161
- G = 138
- B = 184
