140 CSS3 Web Colours

=== by Bob Sutherland ===

Every colour chart I have seen of the 140 named web colours of Cascading Style Sheets version 3 (CSS3) lists the colours in alphabetical order. Why alphabetical order?

Instead of focussing on the names I have tried focussing on the hexadecimal numbers for the RGB (red-green-blue) light intensities. Hopefully you will find my numerically arranged colour charts on this page a bit more useful than an alphabetical list.

If you look at the title above each chart you will see a hint based on the RGB values as to why I grouped those colours together in that particular chart.

I have listed each of the 140 named colours of CSS3 only once somewhere on this page.


All 3 RGB Values are Equal

Chart 111 - Grey Scale
#ffffff - white #f5f5f5 - whitesmoke
#dcdcdc - gainsboro #d3d3d3 - lightgray
#c0c0c0 - silver #a9a9a9 - darkgray
#808080 - gray #696969 - dimgray
#000000 - black

When 2 RGB Values are Equal - Original HTML Colours

The original 16 named and standardized colours in HTML were adopted into the CSS3 list. Twelve of the colours are here and four of the colours (white, silver, grey, black) are shown in the grey scale chart up above.

Chart 80 + 00
#800000 - maroon #800080 - purple
#008000 - green #808000 - olive
#000080 - navy #008080 - teal
Chart FF + 00
#ff0000 - red #00ff00 - lime
#0000ff - blue #ffff00 - yellow
4 Names = 2 Colours
#00ffff - aqua #00ffff - cyan
#ff00ff - fuchsia #ff00ff - magenta

Aqua and Cyan are two different names for the same colour #00ffff.
Fuchsia and Magenta are two different names for the same colour #ff00ff.


When 2 RGB Values are Equal

The chart titles indicate the pattern of the RGB (red-green-blue) light intensities. A 2 represents a brighter light intensity than a 1.

Chart 122
#f0ffff - azure
#e0ffff - lightcyan #afeeee - paleturquoise
#008b8b - darkcyan #2f4f4f - darkslategray

When the RGB Values are Different

The chart titles indicate the pattern of the RGB (red-green-blue) light intensities. A 3 represents a brighter light intensity than a 2, while a 2 is brighter than a 1.

Looking at how many colours there are in the following chart I decided to break Chart 321 up into three separate parts.
