Dear apichai52, For now we're providing only 5 colors of spinners: Green, blue, yellow, red and primary color of your skin. But if you really want to use the white spinner, you have to overwrite one of our already existing spinners color class, for example, the blue one. That's ugly way, but for now, I can't provide you a better way. Add this code to your global styles.scss stylesheet:

.spinner-blue-only {
border-color: #ffffff !important;
}
.spinner-blue-only.mat-progress-spinner svg path {
stroke: #ffffff !important;
}

And then use code:
