Frequently Asked Questions

How do I find the hex code of a color?

You can find the hex code by using our interactive color picker to select your desired shade. As you adjust the hue and saturation, the tool instantly calculates and displays the exact 6-character hexadecimal code for that color.

What is a complementary color scheme?

A complementary color scheme uses two colors that sit directly opposite each other on the color wheel. This creates a high-contrast, vibrant look that is excellent for drawing attention to specific UI elements like buttons or alerts.

How do I check color contrast for accessibility?

Our tool provides built-in contrast checking against WCAG (Web Content Accessibility Guidelines) standards. It compares your foreground and background color choices to ensure text remains legible for users with visual impairments.

What is the difference between RGB and HSL?

RGB (Red, Green, Blue) defines colors based on hardware screen emission, making it standard for digital displays. HSL (Hue, Saturation, Lightness) defines colors based on human perception, making it much easier for designers to intuitively adjust shades and tones.

How many colors should a palette have?

A professional color palette typically consists of 3 to 5 core colors. This usually includes a primary brand color, a secondary accent color, and neutral shades (like dark grays and off-whites) for text and backgrounds to maintain visual balance.

Is this color picker free to use?

Yes, our color picker and palette generator are completely free. You can generate unlimited palettes, convert between formats, and export your CSS variables instantly without creating an account or paying any fees.
