I have looked into the tr function indeed, but thought that sed could do the same thing in this case. I just have a general concern about the use of regular expressions in the tr function, since "Most of the special RE codes do not apply in the tr function. ", so recognising hex color codes could be an issue.
UPDATE: Unless of course you mean that I first need to extract the hex color code, then pipe (|) it through to the tr function?

Is it possible to combine a regular expression with a aritmetical expression? For example, taking a 8-numbers caracter sequece and casting each output of a grep, comparing to a constant.

base32hex
base32::hex(n) Base32 encoding base32::hex(n)
__________________________________________________________________________________________________________________________________________________
NAME
base32::hex - base32 extended hex encoding
SYNOPSIS
package require Tcl 8.4
package require base32::core ?0.1?
package require base32::hex ?0.1?
::base32::hex::encode string
::base32::hex::decode estring
_________________________________________________________________
DESCRIPTION
This package provides commands for encoding and decoding of strings into and out of the extended hex base32 encoding as specified in the
RFC 3548bis draft.
API
::base32::hex::encode string
This command encodes the given string in extended hex base32 and returns the encoded string as its result. The result may be padded
with the character = to signal a partial encoding at the end of the input string.
::base32::hex::decode estring
This commands takes the estring and decodes it under the assumption that it is a valid extended hex base32 encoded string. The
result of the decoding is returned as the result of the command.
Note that while the encoder will generate only uppercase characters this decoder accepts input in lowercase as well.
The command will always throw an error whenever encountering conditions which signal some type of bogus input, namely if
[1] the input contains characters which are not valid output of a extended hex base32 encoder,
[2] the length of the input is not a multiple of eight,
[3] padding appears not at the end of input, but in the middle,
[4] the padding has not of length six, four, three, or one characters,
CODE MAP
The code map used to convert 5-bit sequences is shown below, with the numeric id of the bit sequences to the left and the character used to
encode it to the right. The important feature of the extended hex mapping is that the first 16 codes map to the digits and hex characters.
