<｜begin▁of▁sentence｜>### Instruction:
As a dance instructor, imagine that you are working with a production team to choreograph a dance performance that visually represents a binary tree structure. You have a list of base colors representing different emotions or themes, such as passion, vitality, and tranquility. Given specific indices for a gradient, you need to apply an AdvancedGradientPalette from a dance costume design software to assign corresponding color values to the costumes worn by the dancers portraying each vertex in the binary tree.
### Response:
from igraph.drawing import AdvancedGradientPalette

# Define a new gradient palette with 3 base colors
colors = ['#FF0000', '#00FF00', '#0000FF']  # Red, Green, Blue
indices = [0, 0.5, 1]  # Start, midpoint, end
palette = AdvancedGradientPalette(colors=colors, indices=indices, n=256)

# Use the palette to color vertices of a graph
from igraph import Graph

# Create a simple graph
g = Graph.Tree(8, 2)  # A binary tree of 8 vertices

g.vs['color'] = [palette.get(i / 7.0) for i in range(len(g.vs))]

# Plot the graph with the gradient palette
g.plot(vertex_color=g.vs['color'])
