msa-colorschemes

A bundle of different biological color schemes.

npm install msa-colorschemes --save

How to use

var schemes = require("msa-colorschemes");
// pure mappings
var Clustal = schemes.getScheme("clustal");
> {A: "orange", B: "#fff", ...} 

// dynamic color management
var schemeMgr = new schemes();

var Clustal = schemeMgr.getScheme("clustal");
> { default: "#ffffff",
    type: "static",
    map: {A: "orange", ... },
    getColor = function(letter)
  }
Clustal.getColor("B")
> "#fff"

Add your own scheme

schemeMgr.addStaticScheme("bscheme", {B: "#bbb"})
schemeMgr.getScheme("bscheme").getColor("B")
> "#bbb"

Add a dynamic scheme

var fun = schemeMgr.addDynScheme("fscheme", function(letter,info){
    return info.pos % 2 == 0 ? "#ccc" : "#ddd";
})

var scheme = schemeMgr.getScheme("dscheme")
scheme.type
> "dyn"

scheme.getColor("A", {pos: 1})
> "#ccc"
scheme.getColor("A", {pos: 2})
> "#ddd"
