I have recently started wearing a bright orangey-yellow zip-up top on some of my runs.
I was surprised to discover that this attracts dogs. They come yapping and yelping and circling me and running at me far more than before.
I expect that dogs see in black and white. I don't know how their eyes would see the bright orangey-yellow.
I don't know if there have been any studies on whether dogs are especially attracted to bright clothing and/or it disturbs them? Maybe a study should be carried out by the dog people so the rest of us know what not to wear.
If you are experiencing trouble with dogs, maybe you need to consider whether the colour of your clothing especially attracts/disturbs dogs.
