Changed colors after udating

Hi,
After udpating Radzen.Blazor to version 4.1.8 the colors changed:

<RadzenButton style="width:200px;" Click=@OpenPartnerDialog Text="New Partner" ButtonStyle="ButtonStyle.Success" />

And now buttons are orange.
Could you tell me why, please?

We have updated the themes since Radzen.Blazor 4.0.0. More info is available here.

If you need to use the older version of a theme stick to Radzen.Blazor 3.x.

I see but I use Radzen.Blazor version 4.1.8 and I set ButtonStyle property to ButtonStyle.Success at RadzenButton component and the colore of button is orange and not green.

<RadzenButton style="width:100%;" Click=@OpenPartnerDialog Text="New Partner" ButtonStyle="ButtonStyle.Success" />

I changed this

  <link rel="stylesheet" href="_content/Radzen.Blazor/css/default-base.css">

for this:

  <link href="_content/Radzen.Blazor/css/standard-base.css" rel="stylesheet">

and my problem is solved.
Thank you.
