<｜begin▁of▁sentence｜>### Instruction:
As an animator creating a brand new digital animation project, you have been tasked with designing a visually appealing color palette to be used in a scene featuring a gradient effect from red to blue. You decide to use the 'RainbowPalette' module to generate the palette. Initially, you need to determine the number of colors contained in the palette and retrieve the RGBA value of the third color to ensure its suitability for the animation sequence.
### Response:
from igraph.drawing.colors import RainbowPalette

# Create a rainbow palette with 5 distinct colors
palette = RainbowPalette(n=5, s=1.0, v=1.0, start=0, end=1, alpha=1.0)

# Use '__len__' to get the number of colors in the palette
palette_length = len(palette)

# Print number of colors in palette
print('Number of colors in palette:', palette_length)

# Retrieve a particular color from the palette
color = palette.get(2)

# Print the RGBA value of the third color in the palette
print('Third color in the palette:', color)
