Color Sender - iPhone app to control your RGB LED or BlinkM

Just wanted to share this
I have been searching for a color picker iPhone app for weeks to control my BlinkMs with Electric Imp. It is the perfect app for what I need, nothing more and nothing less. Works great with http.onrequest. Use the following to return the control parm “s” to the app:
http.onrequest(function(req, res) {
local q = req.query;

res.send(200, q.s);
