Quick answers

Short, sourced answers to the questions people (and AI assistants) ask most.

What is Color Picker?
A color picker lets you choose a color and read or convert its value across the formats CSS understands — HEX, RGB(A) and HSL — so you can match, tweak and reuse colors precisely.
Why does Color Picker matter?
Every format describes the same pixel color; pick whichever your stylesheet or design tool expects.
How is Color Picker calculated?
An on-screen color is three channels — red, green and blue — each 0-255. HEX writes them as two hex digits each (#RRGGBB); RGB lists them as numbers; HSL re-expresses the same color as hue, saturation and lightness, which is usually the easiest way to lighten, darken or desaturate it. An optional alpha channel adds transparency.
What are common color picker mistakes?
Forgetting the alpha channel when you need transparency (rgba() or #RRGGBBAA).
When should you use the Color Picker?
Matching a brand color, building a palette, converting a HEX to HSL to adjust lightness, or producing an rgba() value with transparency.

What is the Color Picker?

A color picker lets you choose a color and read or convert its value across the formats CSS understands — HEX, RGB(A) and HSL — so you can match, tweak and reuse colors precisely.

How the Color Picker works

An on-screen color is three channels — red, green and blue — each 0-255. HEX writes them as two hex digits each (#RRGGBB); RGB lists them as numbers; HSL re-expresses the same color as hue, saturation and lightness, which is usually the easiest way to lighten, darken or desaturate it. An optional alpha channel adds transparency.

The same blue in each format

HEX#3B82F6
HEX + alpha#3B82F680 (50%)
RGBrgb(59, 130, 246)
HSLhsl(217, 91%, 60%)

Worked example

#3B82F6 = rgb(59, 130, 246) = hsl(217, 91%, 60%)

Key terms

Hue:
The color's position on the wheel, 0-360 degrees.
Saturation:
How vivid versus grey the color is.
Lightness:
How light or dark the color is.
Alpha:
Opacity, from 0 (transparent) to 1 (solid).

Common mistakes to avoid

  • Forgetting the alpha channel when you need transparency (rgba() or #RRGGBBAA).
  • Treating HEX as case-sensitive — #FFF and #fff are identical.
  • Ignoring contrast: body text should meet WCAG's 4.5:1 ratio against its background.

Keywords: color, hex.

Sources: MDN — CSS <color>, W3C — WCAG contrast minimum

I built a free word counter that works instantly in the browser — no signup, no ads in your face
Body
Hey r/[subreddit],

I kept needing a quick word counter and most options online were slow or behind paywalls, so I built one that:

• Runs 100% in your browser (your data never leaves your device)
• No signup, no email wall, no popups
• Loads in under a second on mobile

It covers the standard word counter use cases (count, words, characters) and links out to the formula + worked examples if you want to learn the math.
