This namespace contiains utilities for interfacing with definitions from 
the book "A Dictionary of Colour Combinations" compiled by Sanzo Wada.

This namespace contains various functions for transforming
  color information across different representations, i.e. the
  way colors can be represented as tuples of numbers.

Note: by default, a "color" is a 3-vec, 4-vec, or 5-vec of numbers
  (with the last entry typically being the Alpha channel) whereas
  the term "Color" refers to the java.awt.Color class.

This namespace contains an implementation of procedural 
  periodic color palettes. It is based on a Inigo Quilez
  article from 1999.

A color palette is simply a unary function that accepts an
  input value and returns an RGB vec. As the input runs 
  from 0 to 1 (normalized palette index), the palette
  oscilates.

This namespace houses higher-order functions for creating
  modulation generators. A modulation generator is a function
  hat accepts timing information and returns a value between
  0.0 and 1.0. Think an ADSR Envelope. 

Supplied values should be considered durations and not
  instances.

The returned modulation generators expect inputs relative to 
  their lifecycle, not relative to the start of the application.
  I.e. pass a diff from when the event happens, not the event 
  time.

Time units are in milliseconds.

Clojure bindings for OpenSimplex2 noise functions.
All functions take an optional seed value and return noise in the range [-1, 1].
When seed is not provided, uses value from global seed atom.

This namespace contains helpers for common periodic waveforms. 

These waveforms are periodic over tau (2 pi) and output values in the 
  range of [-1, 1]. Companion 'normalized' functions are provided which 
  map the output to the range [0, 1].

This namespace differs from 'artlib.modulation as the latter is intended
  for use with some external clock and operates on time values. 
  Additionally, 'artlib.modulation is a set of higher-order functions
  whereas these are simple waveforms.
