Color codes as used on Flight Aware.  Colors are combined with cloud coverage symbols so the cloud coverage symbol appears in the color defining the current Flight Category.

Flight Category Color Codes:

Category Ceiling   Visibility
Low Instrument Flight Rules
LIFR*  (magenta sky symbol)
below 500 feet AGL and/or less than 1 mile
Instrument Flight Rules
IFR  (red sky symbol)
500 to below 1,000 feet AGL and/or 1 mile to less than 3 miles
Marginal Visual Flight Rules
MVFR (blue sky symbol)
1,000 to 3,000 feet AGL and/or 3 to 5 miles
Visual Flight Rules
VFR+  (green sky symbol)
greater than 3,000 feet AGL and greater than 5 miles

*
By definition, IFR is ceiling less than 1,000 feet AGL and/or visibility less than 3 miles while LIFR is a sub-category of IFR.

+
By definition, VFR is ceiling greater than or equal to 3,000 feet AGL and visibility greater than or equal to 5 miles while MVFR is a sub-category of VFR.

 

Cloud coverage symbols:

The cloud cover will either be FEW (1/8 TO 2/8 cloud coverage), SCT (SCATTERED, 3/8 TO 4/8 cloud coverage, BKN (5/8-7/8 coverage), or OVC (OVERCAST, 8/8 Coverage).

Automated stations report "CLR" when clouds may exist above 12,000 feet so a square is used to represent this uncertainty whereas an unfilled circle is used for "SKC" which a human reports the sky is completely clear overhead. The abbreviation "OVX" is unofficial but ADDS uses it here to indicate the sky is obscured which is the case when a METAR reports vertical visibility and no cloud information.
