Don't know.

This is from the NCAA 2006 Div. I Instructions to Umpires (it looks better in the proper format):

10.4 - Uniforms / Equipment
NCAA umpires should take pride in their appearance. Uniforms and hats shall be kept clean, pressed and in first-class
condition. Uniforms will be worn only in the dressing room and on the field. Umpires may not sit in the stands or
enter public areas of the stadium while in uniform.
Each umpire is responsible for his own equipment and uniform. The NCAA will provide one sized NCAA hat to each
regional umpire. Please be sure to fax Honig’s immediately to provide them with your hat size. The hats for the entire
crew will be sent to the host institution and delivered to you upon arrival. The standard uniform options are as
follows:
• Short or long sleeve black pullover shirt with white tipping on collar and sleeve cuff. (reference Honig’s
style HMLS-B, HMLLS-B)
o Black or white T-shirt or mock turtleneck may be worn underneath the black shirt. (All members
of the crew must wear the same color on the bases)
• Short sleeve polo blue pullover style shirt with black and white tipping on the collar and sleeve cuff.
(reference Honig’s style HMLS-LB)
o Black or polo blue T-shirt or mock turtleneck may be worn underneath the polo blue shirt.
o Shiny or dazzle cloth versions are not acceptable.
o All shirts must have the “NCAA” letters embroderied on the left breast pocket
• Black nylon pullover jacket with white shoulder trim and “NCAA” lettering on the left chest. (reference
Honig’s style K-17-B)
o Black, polo blue or white T-shirt, mock turtleneck or turtleneck worn underneath.
• Black blazer.
• Gray pants.
• Black ball bags.
• Black socks.
• Black shoes (white stripes are permitted).
• Black belt.
• Black gloves.
• Black sized hat (each regional umpire will receive one hat)
No other variations are allowed and no conference or association patches are allowed. No uniform numbers will be
worn in regional or super regional tournaments. All base umpires will dress in the same uniform top; the plate umpire
may dress in the uniform top of his choice. However, if all umpires are wearing shirts they must all be the same color.
It is not acceptable to wear a short sleeve shirt on the plate with a long sleeve shirt underneath. No visible
jewelry (excluding wedding bands and medical alert bracelets) or watches of any kind are to be worn on the field during
any NCAA tournament game.
It is acceptable for umpires to wear athletic style sunglasses on the field if the conditions warrant. It is recommended
that umpires carry the glasses onto the field and during the pre-game conference and put them on once they reach their
respective positions.

Then, there's this:

College World Series Umpires
The NCAA will provide sized NCAA hats, shirts, undershirts, and trousers.

so maybe the other colors were provided.
