You know the Dancing Lights cantrip.
Additionally, starting at character level 3, you always have Color Spray prepared, and starting at character level 5, you always have Calm Emotions prepared. You can cast each spell once without a spell slot, and you regain the ability to do so when you finish a Long Rest.
Intelligence, Wisdom, or Charisma is your spellcasting ability for the spells (choose the ability when you select this species).

Choose one of the options below; when you finish a Long Rest, you can choose a new option. Your chosen option changes your skin, hair, or eye color. As a Bonus Action, for the next minute, you shed Bright Light in a 10-foot Emanation originating from you and Dim Light for an additional 10 feet. You infuse the light with your chosen color to provide its benefit, and you can change your chosen color as part of the Bonus Action.

You can use this trait a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.

Blue or Teal. You and your allies within the light have Resistance to Psychic damage and have Advantage on saving throws made to avoid or end the Charmed or Frightened conditions.

Green. When you or your allies in the light regain Hit Points, add your Proficiency Bonus to the number regained.

Orange. Your Speed increases by 10 feet. When an ally starts its turn in the light or enters the light for the first time on a turn, its Speed increases by 10 feet until the end of its next turn.

Pink or Purple. Ability checks made to use the Influence action on an Indifferent creature in the light have Advantage.

Yellow. Double the range of your shed light. You and your allies in the light have Advantage on Intelligence (Investigation) and Wisdom (Perception) checks. The first time an affected creature misses with an attack roll, it can add 1d4 to the total, possibly turning the miss into a hit.

You have proficiency in the Deception, Performance, or Persuasion skill.
