<div>Hi Utkarsh,</div>
<div> </div>
<div>You're indeed right.</div>
<div>Thanks for your help! I had this idea, but I have not been so low in my previous tests, and I was not seeing color evolves.</div>
<div>
<div>However, why is the curvature so important at the edges? I was not aware edges would be kind of singular "points"...</div></div>
<div> </div>
<div>Thanks again!</div>
<div>Regards,</div>
<div> </div>
