Red Foxes are—well, red. I mean really red. But they are elusive, and hard to spot. Camoflage(sp?) is in the intrest of every living thing.
So, how can the little @$$@% hide so well???
And in environments as varied as the forest, swamps, fields, even deserts! 
Red should stand out.
Some are really red, but many are more a rusty brown. They have a lighter belly, but since they don’t lie around on their backs all that often, it doesn’t matter.
Foxes generally hide by not being where you are. They can hear you and smell you. They can see pretty good too. They know where you are in plenty of time to casually amble off. Have you ever seen a deer disappear into the forest? These things are truely big, and they can be elusive as all heck.
Foxes are also kinda small. They can dive down hollow logs and slink behind weeds and brush. When the sit still they are camoflage experts. They fuzziness of them breaks up their silhouette and makes them harder to spot.
They also “hole up” during the day. You don’t see them because they come out at night.
You don’t see foxes because they see you first. Silly.

This is very true. I have often heard that if you see a fox, it’s probably rabid, i.e., sick and disoriented.
You don’t see Redd Foxx 'cause he’s dead. 
Also, many animals lack color vision. That is why you can wear a safety orange and black vest in a camo pattern, and the deer don’t just point and laugh. So, the color may be a lot less imporant than the pattern. Birds, IIRC an exception, they tend to have good color vision enhance the colorful mating displays. My WAG that the primary predators of foxes are wolves and large cats, both of whom trade color vision for enhanced night vision. Somebody who remembers more about cones and rods can explain this in detail.
Just give him a bottle o’ ripple and he’ll figure out how to hide on his own!
They don’t hide. They fake heart attacks and say “Oh, Elizabeth! I’m comin’ for ya! This is the big one!” I don’t know how that stops people from hunting them, but it does.
I thought this was the name of a new computer virus.
Rue DeDay is correct. Avoidance, scent and visual detection and speed are among the fox’s best defenses.
While I’ve seen them many times while riding in a car, I’ve only seen one while out in the wild. I was hiking, and I took a sudden turn off the path to, um, give something back to nature.
There he was, standing in a defile which would have allowed him to watch me from behind had I stayed on the path. When I made eye contact with him, he casually turned around and ambled off into the bushes, and was gone within a couple of seconds.
Bear in mind that foxes are predators, and fairly high up on the food chain. In normal times, their only predator is man. Hiding therefore isn’t their #1 concern (being quick enough to catch their prey is far more important.)
I’ll agree with all of the above ( even the jokesters ), but add a personal anecdote. Not all foxes hide 
.
If they become habituated to people, they can be pretty bold on their own turf. In the case I’m thinking of, their own turf is the landscaped Water Reclamation Plant next to a creek, where I work the graveyard shift 
. And in this case we’re talking about a pair of Grey Foxes, which is a different species ( and genus ) altogether, but otherwise pretty similar habit-wise to Red Foxes.
They’re pretty fearless. They’ll let you walk within fifteen feet of them, staring you down the whole while. Approach any closer and they’ll nonchalantly stroll away. And their justly famed senses not withstanding, I’ve on more than one occasion caused a startled ( and embarassed looking ) fox to hurtle out of a dumpster in our parking lot as I walk by, just a couple feet, while doing my rounds .
My WAG is they watch "How not to be Seen’.
You just don’t see that phrase everyday. I saw it a did a happy dance.

In the resort town of McCall, in Idaho, the local wildlife is largely habituated with the residents and visitors there. The locals like to feed the red foxes eggs.
Of course–now that they’ve gotten a taste for eggs, it’s not uncommon to see a fox darting away from the golf course, with a fresh ‘egg’ in jaws.
