Chromatic Brush

You wave your hand through the air as your paints at your side spring forth, magical paints being summoned in their place, and swipe across an enemy you can see within 60 ft. Make a ranged spell attack against a single creature. On a hit, you choose the damage type, between fire, cold, and poison. Depending on your level, if you can summon more than one brush stroke, 2(5th), 3(11), 4(17), you can choose the damage for each stroke. If two brush strokes are different colors, you may choose to mix the colors, creating a new damage type based on the combination, however, the secondary colors damage is 1d8 less than a primary color. Secondary damages include necrotic, radiant, and acid. If you have three brush strokes, you can combine all three primary colors to create force damage. Consult the picture for more details.
