Riddle Me Colourful

A painted picture in your mind? Click on the title guess and find!

I'm tough and built, one thing in mind,

To push and elevate behind.

Beware the sands of time, and luck,

And muster all your gumph and pluck,

So get a bird, at least a chick.

I'm not the building, but the stick.

'Is the picture clear?'
'Not in the slightest. You need more colours!'
'Well there certainly can't be more than one colour at a time. That would be far too confusing.'
