Typical mistakes

Decidí de quedarme.

Decidí quedarme.

decidir takes the infinitive directly; only the reflexive decidirse adds a preposition: me decidí a ir.

Decidí para el azul.

Me decidí por el azul.

Choosing between options is decidirse por.

Nosotros decidimos ayer y decidimos mañana.

Ayer decidimos, mañana decidiremos.

decidimos is both present and preterite, so the time word has to do the work.
