RMK SLP204 refers to the sea level pressure in hectopascal. Only the tens, units and tenths of hectopascals are included . SLP204 would therefore be 1020.4 hectopascals. The numbers pressure tendency in the previous three hours. BLU is a miltary weather code (BLU is best I think). LAST means its this stations last report (probably due to close for the night)

Colour states: METAR reports from military airfields operated by the RAF, some USAF and others may have a 'colour-code' appended (usually only when ATC is open), which describes the airfield 'fitness': these run from BLU best, through WHT GRN YLO (1 and 2), AMB and RED. The colour is based on the lowest cloud base (usually 3 oktas or more cover, but some use 5 oktas) and the horizontal 'MET' visibility. BLACK is also used, for airfield closed for non-weather reasons.
