Steps to reproduce the behavior

In the documentation it states that this can be changed by applying following condition:

<p-progressSpinner></p-progressSpinner>

@keyframes p-progress-spinner-color {
    100%,
    0% {
        stroke: #d62d20;
    }
    40% {
        stroke: #0057e7;
    }
    66% {
        stroke: #008744;
    }
    80%,
    90% {
        stroke: #ffa700;
    }
}

The two below examples are working locally but not in stackblitz for unknown reason:

<p-progressSpinner styleClass="custom-spinner"></p-progressSpinner>

@keyframes custom-progress-spinner-color {
    100%,
    0% {
        stroke: #d62d20;
    }
    40% {
        stroke: #0057e7;
    }
    66% {
        stroke: #008744;
    }
    80%,
    90% {
        stroke: #ffa700;
    }
}

It is also possible to change that it can only have one color:

.p-progress-spinner-circle {
  stroke: #d62d20 !important;
}

which makes it kind of basic but fine.

Expected behavior

Be able to change the transition colors of the ProgressSpinner.

• Find out what works to change the color
• Change the description of what actually works in the documentation
• Check that other properties aren't affected in the same way
