The problem of accurate rendition of colours is quite complex and involves interaction between the browser, the host windowing environment and the actual specification.
Netscape will only accurately render, it is claimed, colours which have RGB values that are one of the hexdecimal pairs 00, 33, 66, 99, CC and FF. This gives a total of 63 ( = 216) possible colours. The following table displays all the colours.

Note. This refers to colours used for text and background rendering, not image rendering. If you see any errors in the display above, they may only show because this page is attempting to use 216 different text/background colours which is unlikely on a normal page.
Unlike all the other pages in the Encyclopaedia this page is displayed using the browser default text and background colours.
You may find it interesting to start up other windows applications whilst viewing this page and note the effects on colour map resources.

NN and OP2 undoubtedly handled this best. ARA seemed only to
support 16 colours, IE mis-rendered some colours and MOS3 crashed
