How to convert my design from RGB to CMYK?

1 What is RGB and CMYK

RGB refers to the primary colors of light, Red, Green and Blue, that are used in monitors, television screens, digital cameras and scanners. CMYK refers to the primary colors of pigment: Cyan, Magenta, Yellow, and Black. These are the inks used on the press in "4-color process printing", commonly referred to as "full color printing" or "four color printing".

What is the difference between the RGB and CMYK color space and why does it matter?

Simply put, CMYK is the color mode intended for printing with ink, such as business card designs. RGB is the color mode intended for screen displays.

The more color added in CMYK mode, the darker the result. The more color added to RGB, the lighter the result.

CMYK has a numerical range of 4x100; RGB has a numerical range of 3x256. Therefore, the energetic colors that RGB can produce are difficult to reproduce in CMYK.

When designing, the biggest mistake you could make is forgetting to convert to the appropriate color mode for your project. If you forget to do this, colors could appear washed out or too vibrant.
