Directions, sizes and colours.

Points and numbers

Every constant and named colour, with its value.

• Vec(): A 3D vector such as UP or [1, 2, 0]; adds, subtracts and multiplies like a numpy array.
  • .tolist(): The three numbers as a list.
• Point(tree): A point the preview works out from a formula; await it for [x, y, z].
• Expr(tree, shape="v"): A number or point the preview works out (m.width, c.get_center()); use it in sums and placement, or await it for the numbers.

Colour helpers

• interpolate_color(a, b, alpha): The colour alpha (0 to 1) of the way from one colour to another.
• color_gradient(colors, length): length colours in steps through the colours given.
• average_color(*colors): The mix of several colours.
• rgb_to_color(rgb): A colour from [r, g, b], each 0 to 1.
• color_to_rgb(color): A colour as [r, g, b], each 0 to 1.
• ManimColor(value): A colour from a name, hex string or [r, g, b] (for scripts that use it).

Constants

Colours

Every named colour. GREY and GRAY spellings both work. A hex string such as "#ff8800" works anywhere a colour does.
