If I'm grabbing colours from a screen that uses 3 link colours:
1) Highlighted (aka mouseover)
2) Followed
3) Unfollowed (aka initial)
how do I grab the colour from the followed and unfollowed links? As soon as the pointer touches a link, it becomes Highlighted.

You're correct that it's a little tricky to grab colors of unhighlighted links as rolling over would change the color. What I suggest that you do is the following.

1: Open the web page you want to grab color from and press the 'Print Screen' button on your keyboard. It's usually on the top row on the right.

2: Open any graphics program, for example Paint of Adobe Photoshop.

3: From the 'Edit' menu select 'Paste' or press 'Ctrl' and 'V' on your keyboard.

4: An image of the web page will appear in your graphics program, and then you can use ColorPic to pick the color from the image.

I hope this helps.

this requires a feature request:
"ReGrag last location" button
meaning ColoPic will sample the color at the exact coordinates as last sample, even if the mouse is elsewhere

Thats an interesting idea. It might also be done as a delayed grab. I'll consider this for the next version. Thanks for the feedback.
