How do I convert HEX to RGB?

Split the 6-digit HEX code into three pairs. Convert each pair from base-16 to base-10. Example: #FF5733 → R=255, G=87, B=51. Or use PickConverter's free Color Converter for instant results.

What is the difference between RGB and HEX?

They represent the same colors in different formats. HEX uses a 6-digit hexadecimal code (e.g. #FF5733). RGB uses three decimal values 0–255 (e.g. rgb(255, 87, 51)). Both are used in CSS.

When should I use HSL instead of RGB?

HSL (Hue, Saturation, Lightness) is easier to adjust intuitively. To make a color lighter, increase L. To make it more vibrant, increase S. It's great for theming and design systems.

What color format does print design use?

Print design uses CMYK (Cyan, Magenta, Yellow, Key/Black). RGB and HEX are for screens. When preparing files for print, always convert to CMYK to avoid color shift.

RGB	`rgb(255, 87, 51)`	CSS, digital screens
RGBA	`rgba(255,87,51,0.8)`	CSS with transparency
HSL	`hsl(11, 100%, 60%)`	CSS, design systems
CMYK	`0%, 66%, 80%, 0%`	Print / offset printing

How to Convert HEX to RGB Manually

A HEX color is 6 hexadecimal digits. Each pair represents one color channel (Red, Green, Blue). Convert each pair from base-16 to base-10:

#FF5733
 ^^   →  FF = (15×16) + 15 = 255  (Red)
   ^^  →  57 = (5×16)  + 7  = 87   (Green)
     ^^→  33 = (3×16)  + 3  = 51   (Blue)
Result: rgb(255, 87, 51)

When to Use Each Color Format

HEX — Most common in web CSS. Short to write, widely supported. Use for simple color values.
RGB / RGBA — When you need to control opacity (rgba) or calculate colors programmatically.
HSL — Best for design systems. Adjusting the L value lightens/darkens color predictably.
CMYK — Required for print. RGB colors look different when printed — always convert for print design.

Same color, different notation. #FF5733 (HEX) is the same as rgb(255, 87, 51). Both work in CSS.

Use HSL when building a design system or theme — adjusting Lightness makes colors lighter/darker predictably, which is harder with RGB or HEX.

CMYK. Always convert from RGB to CMYK before sending files to print to avoid unexpected color shifts.
