What is HEX color format and how does it work?

HEX is a hexadecimal color notation using 6 characters (or 3 for shorthand). Each pair represents Red, Green, and Blue values from 00 to FF (0-255 in decimal). Example: #FF5733 means Red=255, Green=87, Blue=51. It's the most common format in web development.

What is RGB color format?

RGB stands for Red, Green, Blue. Each channel has a value from 0 to 255, representing the intensity of that color component. Example: rgb(255, 87, 51). RGB is intuitive for programmatic color manipulation and supports transparency with RGBA.

How do I convert HEX to RGB online?

Enter your HEX color code (like #FF5733 or FF5733) in the input field. The tool instantly converts it to RGB format (255, 87, 51). You can also use the color picker to select a color visually and see both formats.

How do I convert RGB to HEX online?

Enter your RGB values (0-255 for each channel) or use the sliders. The tool instantly converts to HEX format. Example: RGB(255, 87, 51) becomes #FF5733. Each decimal value is converted to its two-digit hexadecimal equivalent.

What is the difference between #RGB and #RRGGBB?

The 3-character format (#RGB) is shorthand where each character is doubled. For example, #F00 equals #FF0000 (red), #09F equals #0099FF. Only works when each pair has identical digits. 6-character format is more precise.

How do I convert HEX to RGB manually?

Split the HEX into pairs (RR, GG, BB) and convert each from hexadecimal to decimal. FF=255, 00=0, 80=128. Example: #3B82F6 → 3B=59, 82=130, F6=246 → rgb(59, 130, 246). Use a hex calculator or this tool for accuracy.

Why use HEX over RGB in CSS?

HEX is more compact (6 vs 11+ characters), widely used in design tools, and is the traditional web format. RGB is more intuitive for programmatic manipulation, easier to read individual channels, and required for transparency (RGBA).

Can I use transparency with HEX and RGB?

Yes! Use RGBA for RGB with alpha: rgba(255, 0, 0, 0.5) for 50% transparent red. Use 8-character HEX: #FF000080 (last two digits are alpha, 00=transparent, FF=opaque). Both are widely supported in modern browsers.

What does each RGB value represent?

R (Red), G (Green), B (Blue) each range from 0 (none of that color) to 255 (full intensity). Mixing these primary colors of light creates all visible colors. 0,0,0 is black, 255,255,255 is white, equal values create grays.

Is the HEX to RGB conversion lossless?

Yes, HEX and RGB represent the same color space (sRGB). Converting between them is mathematically exact with no quality loss. Both formats can represent exactly 16,777,216 colors (256³).

What is the CSS rgb() syntax?

Modern CSS supports both rgb(255, 0, 0) and rgb(255 0 0) syntax. The space-separated format is newer and also supports alpha: rgb(255 0 0 / 50%). Legacy comma syntax: rgba(255, 0, 0, 0.5).

How do I get black, white, and gray in HEX and RGB?

Black: #000000 or rgb(0, 0, 0). White: #FFFFFF or rgb(255, 255, 255). Gray uses equal values: #808080 or rgb(128, 128, 128). Lighter grays have higher values, darker grays have lower values.

What are the primary colors in RGB?

RGB primary colors are Red (#FF0000), Green (#00FF00), and Blue (#0000FF). Secondary colors: Yellow (Red+Green=#FFFF00), Cyan (Green+Blue=#00FFFF), Magenta (Red+Blue=#FF00FF). White is all three at full intensity.

Can I convert HEX/RGB to other formats like HSL?

Yes! Use our Color Picker tool which converts between HEX, RGB, HSL, HSV, and CMYK. HSL (Hue, Saturation, Lightness) is often more intuitive for creating color variations and design work.
