Yes—but usually indirectly. Phase-detect autofocus primarily responds to contrast/tonal differences within the active AF point, not color by itself. If the subject area under the AF point has weak contrast against the background, or low internal detail, the camera may hunt.

That’s why some outfit colors seem easier: certain colors and brightness levels create stronger contrast with the rink/background, while white, gray, pastel tones, or some blacks may provide less usable contrast in the specific area the AF point is reading. AF points also sample only a small part of the frame, so small changes in where the point lands can matter a lot.

There can also be some camera-specific spectral sensitivity differences in AF sensors, so particular colors may be detected a bit better or worse, but contrast is the main factor.

Practical takeaway: place the AF point on an edge or textured area with strong contrast (seams, patterns, face/helmet edges, skate details) rather than a flat patch of clothing. If a subject causes hunting, it’s usually because the AF system isn’t seeing enough clear contrast where you’re asking it to focus.
