What is a Color Picker?
A Color Picker is a tool that helps you select any color and instantly generate its exact color codes. It is widely used in web design, UI/UX development, branding, graphic design, marketing creatives, and printing projects. Instead of guessing the color values manually, a color picker gives you accurate codes in multiple formats such as HEX, RGB, HSL, and CMYK.
This free Color Picker tool by Oneclikdeal Toolkit is designed for speed and simplicity. You can choose a color from the built-in color selector or paste any HEX code to convert it instantly. The tool works directly in your browser, which means your inputs stay private and are not uploaded to any server.
Why Color Codes Matter in Web Design and Branding
Colors play a major role in user experience and conversion rate optimization. For example, the color of a button can impact how many people click it. Branding colors also build trust and recognition. Companies like Facebook, Twitter, and YouTube use consistent colors to create a strong identity across websites, apps, and marketing materials.
When working with developers or designers, using exact color codes avoids mistakes. If you share a color by saying “use blue,” everyone may choose a different shade. But if you share the exact HEX or RGB code, the color will remain consistent everywhere.

HEX vs RGB vs HSL vs CMYK (Simple Explanation)
Different platforms use different color systems. That is why this tool provides multiple formats. Here is what each format is used for:
- HEX: The most common format used in websites, CSS, and design systems. Example:
#FF5733. - RGB: Used for digital screens. It represents Red, Green, and Blue values. Example:
rgb(255, 87, 51). - HSL: Useful for adjusting color tone. It stands for Hue, Saturation, and Lightness. Example:
hsl(10, 100%, 60%). - CMYK: Used in printing and packaging. It stands for Cyan, Magenta, Yellow, and Black. Example:
cmyk(0%, 66%, 80%, 0%).

How to Pick the Best Colors for High Conversion Landing Pages
If your goal is to generate revenue from Tier-1 countries (USA, UK, Canada, Australia), color selection can impact your results. High-performing landing pages usually use strong contrast between background and call-to-action buttons. For example, a bright orange or green button on a clean white background often increases attention.
A good rule is to keep your main brand colors limited to 2–3 primary colors and then build lighter and darker shades around them. HSL format is extremely helpful for this because you can adjust lightness and saturation while keeping the same hue.
Why Do Colors Look Different on Screen vs Print?
Many people are surprised when a color looks perfect on screen but prints differently. This happens because screens use light (RGB), while printers use ink (CMYK). Paper quality, printer settings, and color profiles also affect the final output.
If you are printing brochures, packaging, or business cards, always use CMYK values and test with a sample print. This tool helps you quickly generate CMYK from HEX so your print designs stay consistent.
