White's strengths are a roster of small creatures that are strong collectively: protecting those creatures with enchantments, gaining life, preventing damage to creatures or players, imposing restrictions on players, reducing the capabilities of opposing creatures, and powerful spells that "equalize" the playing field by destroying all cards of a given type.The more colors you choose for your deck to incorporate, the higher the chance that you will encounter a situation where you will be unable to cast one or more of the spells in your hand due to lacking one (or more) of the colors of mana those spells require in their “mana cost”.

You will be able to cast “Colorless” spells (spells that have no colored mana symbols in their “mana cost”) regardless of the color(s) you choose.

Play around on sites like MTGDeckBuilder and MTGVault.
