How to reset color

I want to undo all the changes I've made and looked all over for a reset button and haven't found it.
also I was looking at a video about color and contrast and it suggested turning on the display qualifier focus and hovering over the image on the color page, but when I do so, I just still have an arrow and not like what was expected, as nothing happens.

In the Color page click on the Color drop down menu and click on Reset. You will be presented with a choice.

The Color Picker is for selecting a particular color in the frame and applying it to things such as the Curve and Custom Color controls in the Color page, and selecting a color and applying it to a background or text, etc. If you enter Color Picker in the search bar of the Reference Manual all the entries for Color Picker will be shown.

thanks. I found that by highlighting all the clips and choosing remove attributes, I could select color correction. Is one way better than another?
