white-on-yellow text in the yellow's slice controller

Is this specifically Slicer Dark style? I have a memory of everything being dark text but I’m typically using Slicer light style.

@lassoan I can't really tell that the PushPin looks any blurrier than the original PNG file when I view them side-by-side. Maybe the blurriness you are seeing is the same as what is inherently in the PNG file?

I'm not sure what I could do if it the issue is inherently in the original source file. I could swap it out for the Material Symbol's Push Pin SVG.

Is it only the PushPin icons that look blurry? Or do any of the other icons in the Slice view controller look blurry to you?

The pushpin icon did not look nice before but since it is bigger now, the low quality has become more noticeable. All the other icons in the slice view controller are good, only the pushpin icon looks bad (probably because the other icons don't have any curved lines, so they scale perfectly). We already have a number of SVGs coming from the material icon set and they appear nicely at various resolutions, so hopefully the SVG icon will work well here, too.
