Hue Bar

Description

Implement the hue_to_tile and the hue_bar functions to produce the following graphic.

hue bar

This is a hue bar consisting of 360 tiles, each tile is a rectangle, colored with a fully saturated (saturation 1.0) fully light (value 1.0) color in the corresponding hue (0 to 359). Use the pytamaro hsv_color function to create the color from the hue, saturation, and value.

The hue_to_tile function

This function should return a rectangle of the given width and height. The color of the tile is composed of the given hue, a saturation of 1, and a value of 1, using the pytamaro hsv_color function.

Assert that the value of the hue parameter is acceptable (between 0 and 360).

The hue_bar function

This function takes the wanted tile_width and tile_height for each of the 365 tiles, and it produces 360 hue tiles corresponding to each hue value from 0 to 359. Ultimately it returns a Graphic with each tile placed beside the other.

To achieve this you can use a for-loop.

In each step of the loop you want to create a tile of a different hue, and place it beside the previous tiles.

Use the result variable to store the graphic containing all the (previous) tiles together.
