- In some cases,repparttar colors that aren't available will be converted to their nearest "color-safe" equivalent. This can lead to your web page looking different from what you intended.

- In other cases, particularly for large areas of continuous color (such as backgrounds and tables),repparttar 143606 browser may attempt to simulaterepparttar 143607 your chosen color by "dithering" two or more color-safe colors together. This usually makesrepparttar 143608 colors look grainy, and very often looks absolutely terrible. If you don't know what I mean by "dithering", seerepparttar 143609 explanation at:

The Solution:

Review your HTML coding, and look atrepparttar 143610 colors in each COLOR= attribute... then change them to their closest color-safe equivalents.

(You might want to make a safe copy of your web pages before doing this, in case you make an oopsy).

Understanding The COLOR Attribute In HTML Code:

If you look atrepparttar 143611 COLOR= attributes inrepparttar 143612 HTML code, it usually looks something like this


(Sometimes you may also see named colors like "RED" or "MAGENTA" which is beyondrepparttar 143613 scope of this discussion, just skip over any of those).

The values inrepparttar 143614 quotes afterrepparttar 143615 hash symbol, are actually three pairs of digits, representingrepparttar 143616 Red, Green, and Blue components ofrepparttar 143617 color expressed as hexadecimal numbers inrepparttar 143618 range 00 to FF.

So forrepparttar 143619 color given above:

- C2 isrepparttar 143620 Red component - 0F isrepparttar 143621 Green component - 8C isrepparttar 143622 Blue component

There is also a three-digit variant ofrepparttar 143623 above which you may very occasionally run across:

If you see something like: COLOR="#F9C"

Then you simply need to repeat each digit, thus F9C represents:

- FF forrepparttar 143624 Red component - 99 forrepparttar 143625 Green component - CC forrepparttar 143626 Blue component

Converting to Color-Safe Colors:

Now we understandrepparttar 143627 theory, we're ready to convert a color to its closest color-safe equivalent.

For each ofrepparttar 143628 Red, Green and Blue components, you need to convert them separately into values, you need to convert them separately intorepparttar 143629 color-safe equivalents, and then recombinerepparttar 143630 whole lot together.

The conversion step goes like this:

00 to 19 - converts to 00 1A to 4C - converts to 33 4D to 7F - converts to 66 80 to B2 - converts to 99 B3 to E5 - converts to CC E6 to FF - converts to FF

For example:

If we need to convert C20F8C to its closest color-safe equivalent:

- We would convertrepparttar 143631 C2 part to CC - We would convertrepparttar 143632 0F part to 00 - We would convertrepparttar 143633 8C part to 99 - And thus we would CC0099 asrepparttar 143634 final color.

Some other examples:

2B2CF0 would convert to 3333FF C000C0 would convert to CC00CC F0A000 would convert to FF9900 And so on...
