A picture of the color would help..??
You could go with monochromes, like blues/greens/ocean colors.
You could go with a color triad- the dark teal with orange and pink.
Lastly, you could go with a split complement: take the 2 colors on either side of the dark teal (I would think blue and green) and use the dark teal's opposite color (peach).
If you used a good variety of shades of each color- regardless of what you make, I think it would be lovely!
