Filter valid hexadecimal color codes

So I have a text file containing valid and invalid hexadecimal color codes. Would I need to build a custom c program to filter the valid color codes or would a standard unix command achieve this?

NAME
massagevendor - convert the ethernet vendor codes master list to arpwatch format SYNOPSIS
massagevendor vendorfile DESCRIPTION
massagevendor is a program that converts a text file containing ethernet vendor codes into a format suitable for use by arpwatch(8) and arpsnmp(8). The input vendorfile is a master text file containing vendor codes. The output is sent to stdout. Each line of the vendorfile is expected to have a six digit hexadecimal vendor code followed by spaces followed by the name of the manufacturer. All ethernet devices have a unique identifier which includes a vendor code specifying the manufacturer of the device. In normal operation arpwatch(8) and arpsnmp(8) use the file ethercodes.dat to report this vendor code. massagevendor is used to generate the ethercodes.dat file from text files containing these vendor codes. Locations where an ethernet vendor codes master text file can be obtained are given below. FILES
/var/lib/arpwatch - default location of the ethernet vendor list ethercodes.dat - file containing the list of ethernet vendor codes SEE ALSO
arpwatch(8), arpsnmp(8) NOTES
Sources for ethernet vendor codes seen in the wild are http://map-ne.com/Ethernet/vendor.html ftp://ftp.cavebear.com/pub/Ethernet.txt http://www.cavebear.com/CaveBear/Ethernet/vendor.html Useful for comparison or completeness are the ethernet vendor codes as assigned by the IEEE which can be found at http://standards.ieee.org/regauth/oui/oui.txt BUGS
