This activity uses X and Y coordinates of an pixel and converts it into RGB value. Then using the RGB value, it tries to find the nearest color. The algorithm used to find the nearest color is Euclidean Distance Formula.Custom activity offers these two features:<ol><li>Extract color from any pixel on the screen</li><li>Extract colors from image</li></ol>There are two Color Scheme used in this activity:<ol><li>PrimaryColor - enum consists of 12 primary colors</li><li>KnownColor - Default Color enum in System.Drawing</li></ol>

Identify color using the Euclidean Distance formula

HiWhat should be the input for 'Image' field of this activity? RegardsVikas

Hi, what is the datatype of variables for setting up the cordinates

I just wanted to ask whether you can make an output for the RGB code of the color you capture as well?

how do I work with the activity - extract color from image,

when I put a variable it out-put all the dictionary.

I try to use this component to detect color from web screen. It return only White even X Y  position change.

- Open browser (ex. https://colorhunt.co/)

- Attach browser ( page of https://colorhunt.co/)

- Get position (select some position of color)

- message box (Show only white even X.Y was changed)

hand utility that saved me some time! - This will take a colour on the screen and approximate it - which is very important when doing colour operations. 
One improvement would be to make it more flexible, so rather than only supporting what colours are on the screen, having the ability to pass it any image. 


This is a very handy component. I have used good use of this to capture colors from screen. 
Amazing work!!!

It can be used for color verification of Test Suite.Thank you.

Thank you for such a useful activity. I used position directly from html code as with activity GetPosition I did not know how to  work with gained variable. But your code is easy to use and helps a lot.
