We can loop over a list of colors and tell Tina to turn that color.

Run this program, and see where the colors come from. What happens if you add or remove colors from the list?
```python.run
import turtle
tina = turtle.Turtle()
tina.shape('turtle')
colors = ["red", "orange", "yellow", "green", "blue", "purple", "black"]
for each_color in colors:
angle = 360 / len(colors)
tina.color(each_color)
tina.circle(40)
tina.right(angle)
tina.forward(30)
```
Want to make this program your own? Change what tina does inside the `for` loop. What else could she do for each color?
