Function hex

A template tag function for converting hexadecimal color codes to Vector4 colors. Here are some examples of how it can be used:

// Regular 6-digit format:
hex`FF0000` // Red, is converted to [1, 0, 0, 1]

// Short 3-digit format:
hex`F00` // Red, equivalent to FF0000

// 8- and 4-digit formats for controlling the alpha value:
hex`00FF007F` // Half-transparent green
hex`FF0F` // Opaque yellow, equivalent to FFFF00

// The color codes are case-insensitive:
hex`58f` // Sky blue, equivalent to 5588FF
hex`fF0eaB` // Magenta, equivalent to FF0EAB

// Usage in properties:
new LinearProperty(true, [
  new Keyframe(0, hex`f00`),
  new Keyframe(1, hex`0f0`),
  new Keyframe(2, hex`00f`),
  new Keyframe(3, hex`f00`),
])
