Can I edit default color in my dashboard panel for each bar having same field?

[admin51]

Is It possible to apply different color visualization for both "Yes" and "No" graph having same field "count"?

I tried using the following code, but It didn't change.

<option name="charting.fieldColors"> 

{​​​​​​​​"count:Yes": #0000FF , "count:No": #FFA500}​​​​​​​​ </option>
