Sampling Colour from Web for replace colour function

[taxboy]

Not strictly a photography issue but any help appreciated

I'm looking to redecorate the masony on the outside of the house and thought one way to get a rough idea of coulour would be take a pic of the exterior and then use the replace colour function using the shade colours from Dulux etc from their web page. I appreciate I won't get an exact match but should be bear enough to get a rough idea

Is there a quick way of sampling a colour from a web page to just click into PS. I'm currently having to create a new blank document drag the eyedropper to the web page and then make a note of the RGB values. I'm sure there's an easier way

Take a screen grab and open that in PS; then use the sampler?

Chrome and Firefox have a color picker plugin, does exactly what your after. (Note it's the American spelling of colour)

Thanks for the suggestions I've cracked it now - wasn't keeping the mouse button down when moving fron PS window to browser window
