1) Open the attached archive or create your own

2) Enable Colour Management via the Color Manager palette

2) Within the Color Manager palette, set 'Display Device' to default
 
3) Create a Basic > Color procedural layer at the top of your layer stack 

4) Set your lighting to flat via the overhead toolbar

5) Open the colour picker on the procedural layer and select a colour with 'canvas' set to 'Pick Screen Pixels'

6) Use the eye dropper to select the colour from the geometry in the viewport
