Tap For One White Mana

I'm not racist, I swear! (I have black friends!) Every Magic: The Gathering player knows that you tap the Plains cards for "white mana" to cast spells.
Truth be told, the spell I could really use right now is "Time Control", which requires blue mana. After an unscheduled overnight detour in the Rockies, I'm running way behind schedule as I cross Kansas. Can I make it home in time to pick up my son from school tomorrow? Maybe with a Mesa Pegasus.
