// requires SoftMoon.WebWare.rgb  (JS_toolbucket/SoftMoon-WebWare/rgb.js)

//this function:
// • requires passing in a 6-digit hexadecimal RGB string or a 3-value integer-byte RGB array
// • returns an array of hexadecimal RGB string values → [protan, deutan, tritan]
// The returned array ☆simulates☆ colorblind vision for people with “full color” vision.
// The returned array-Object has 2 additional properties:
// • low
// • high
// Since the returned colorblind values are interpolated from a limited data pool,
// these low/high properties are the arrays [protan, deutan, tritan]
// of the “nearest” websafe colors from which the interpolated values are calculated.
// I’m looking forward to finding a better formula to calculate the values directly… … …
// Or perhaps converting to Hue-Chroma-Gray and interpolating those values would be better…but slower.

SoftMoon.WebWare.rgb_to_colorblind=function(h)  {
	if (typeof h == 'string'  &&  SoftMoon.RigdenColorblindTable[h])  return SoftMoon.RigdenColorblindTable[h];

		x=(typeof h == 'string') ? parseInt(h.substr(i*2, 2), 16) : h[i]; // alert(x);
		ws[i]=0x33*Math.floor(x/0x33);
		rgb[i]=(x-ws[i])/0x33;  }     // alert(h +'\n'+ SoftMoon.WebWare.rgb.to.hex(ws));
	cb.low=SoftMoon.RigdenColorblindTable[SoftMoon.WebWare.rgb.to.hex(ws)];
	for (i=0; i<3; i++)  {if (ws[i]<255)  ws[i]+=0x33;}  //cycle through  r, g, b
