RGB/CMYK Conversion

Tool Introduction

"RGB/CMYK Conversion" is an efficient and convenient online bidirectional color code conversion tool. Whether you are a designer, developer, or content creator, you can easily convert RGB color codes (e.g., for web and screen display) to CMYK color codes (for printing), and vice versa, using this tool. This tool supports two mainstream functional color code input formats: rgb(R, G, B) and cmyk(C, M, Y, K), helping you quickly and accurately obtain the desired color values.

How to Use

1. Select Conversion Direction: This tool supports bidirectional conversion. If you want to convert RGB to CMYK, enter the RGB value in the "RGB Code" input box; if you want to convert CMYK to RGB, enter the CMYK value in the "CMYK Code" input box.
2. Enter RGB Code: Enter a standard RGB color value in the "RGB Code" input box, in the format rgb(R, G, B), for example: rgb(124, 96, 200). The values of R, G, B are integers between 0-255.
3. Enter CMYK Code: Enter a standard CMYK color value in the "CMYK Code" input box, in the format cmyk(C, M, Y, K), for example: cmyk(38, 52, 0, 22). The values of C, M, Y, K are integers or floating-point numbers between 0-100.
4. View Results: After entering a color code on either side, the input box on the other side will automatically display the converted corresponding color code in real-time.

Input Parameter Format:

• RGB: rgb(R, G, B), where R, G, B are integers from 0-255.
• CMYK: cmyk(C, M, Y, K), where C, M, Y, K are integers or floating-point numbers from 0-100.

Output Result Format:

• RGB conversion result is: rgb(R, G, B).
• CMYK conversion result is: cmyk(C, M, Y, K).

Frequently Asked Questions

• Q: What input formats does this tool support?
• A: This tool mainly supports two functional color code formats: rgb(R, G, B) (R,G,B values range 0-255) and cmyk(C, M, Y, K) (C,M,Y,K values range 0-100).
• Q: What is the format of the output result?
• A: The output format is consistent with the expected format of the input box, i.e., RGB converts to rgb(R, G, B) format, and CMYK converts to cmyk(C, M, Y, K) format.
• Q: What is the conversion accuracy between RGB and CMYK?
• A: This tool uses industry-standard algorithms for color conversion, providing high accuracy. However, please note that since RGB and CMYK are different color gamut models, some colors may have subtle visual differences between different models.

Notes

• Please ensure that the entered RGB or CMYK code format strictly complies with the requirements; incorrect formats may lead to conversion failure or inaccurate results.
• RGB values should be between 0-255, and CMYK values should be between 0-100. Entering values outside these ranges may lead to unexpected conversion results.
• This tool is an online converter, no software or plugins need to be installed, ready to use.

Origin and Differences of RGB and CMYK

RGB (Red, Green, Blue) is an additive color model, commonly used for screen display devices such as televisions, computer monitors, mobile phones, tablets, etc. It produces various colors by superimposing red, green, and blue primary light; when the three primary lights are superimposed equally, white is produced. RGB color values are usually expressed in the range of 0-255, representing the intensity of light. Its characteristics are vibrant colors, high saturation, and the ability to display a wide color gamut.

CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive color model, primarily used for printing. It forms colors by cyan, magenta, and yellow inks absorbing light. Theoretically, equal superposition of the three primary inks would produce black, but in actual printing, it often tends towards dark brown. Therefore, black (K) ink is additionally added to provide purer black and richer details. CMYK color values are usually expressed as percentages, ranging from 0-100%. Its characteristics are that color reproduction is limited by ink and paper, and the color gamut is relatively smaller than RGB.

When to Use RGB, When to Use CMYK

Understanding the differences between RGB and CMYK is crucial for choosing the correct color mode:

• Use RGB: When your design work is primarily for electronic screen display, such as web design, UI interfaces, digital advertising, video content, emails, etc. In these scenarios, using RGB ensures color accuracy and vibrancy.
• Use CMYK: When your design work needs to be physically printed, such as brochures, posters, business cards, book covers, packaging design, etc. Before sending files to the printer, converting the design to CMYK mode is an essential step, which helps avoid color differences in printed materials and ensures that the printing effect meets expectations.
