human? ain't that the truth... my Rottie simply would NOT walk on any grating unless it had real small holes, and at 125lbs, he didn't like to be carried either

Over the last 50 years dozens of pet dogs have leapt from the 50ft bridge for no apparent reason, usually on clear sunny days. Each of the dogs jumped from the same spot between two parapets on the right-hand side. In 2005 the problem was so bad that 5 dogs jumped to their deaths off the bridge within the space of 6 months. The SSPCA ( Scottish Society for the Prevention of Cruelty to Animals ) considers the matter a 'heartbreaking mystery'.
Many theories have been proposed to explain these peculiar circumstances. Some people believe that the dogs have jumped because the bridge is haunted, they they were perhaps lured by an otherworldly scent. One story suggests that in 1994, a local man threw a baby from the bridge because he believed him to be the anti-Christ. Celtic mythology also attributes an otherworldly feel to the area with Overtoun being considered a 'thin place' between Heaven and Earth

As I'd noted, their resolving power (i.e. acuity) is on average about what humans would experience with about 20/80 vision, but they are far more sensitive to motion, light and shadow. Some dogs (greyhounds, salukis, etc.) are considered "sighthounds" and hunt primarily by sight, so I'd assume they may have a sharper acuity than other breeds. Having owned a greyhound at one time, I can say that their hearing is quite sharp as well, although their sense of smell is somewhat diminished in comparison to other breeds I've owned.
No, I didn't drop nuthin off that bridge.
So my guess is that the dog hears something on the other side of the rail that excites his interest enough that he leaps over the railing not knowing that there is a big drop on the other side.
My sister knows someone who lost one of their agility dogs off the edge of a parking ramp. Not sure which level they were on, but the dog jumped over the ledge, also not aware that the ground level was not the same on the other side.
Have also read of several police dogs in cities either going the little half walls on the roofs of buildings or off of parking ramps to their demise. :-(
The idea of a suicidal dog just doesn’t sit right with me.
A dog that doesn’t realize that it is on a bridge over a river gorge is easy to understand and believe.
A dog doesn’t think like a human. If he doesn’t see a drop off he doesn’t infer from other cues that it is there.
We are talking about the way dogs perceive the color of objects, hence reflected light, or in your example “paint”.
I can tell you learned your colors after the advent of color computer monitors. You’re speaking of luminant color. Red, green, blue. White is the totality of color and black is the absence of it.
However, RGB are not primary colors when speaking of reflectance, and that is the standard for everything that is not a light source in and of itself. Red, yellow and blue are primary. Green would be secondary because it’s the combination of yellow and blue. Same for orange, which is red and yellow. Same for purple, red and blue. Colors that are more subtle yet are tertiary colors, involving all three primary colors.
If you’ve ever mixed paint, colored with crayons or magic markers, you were using these colors and not RGB. Red and green makes brown in the world of reflectance. Green and blue makes teal or aqua, depending upon proportion. Black is all three and is the totality of color, at least in theory. Printers have to use a dedicated black ink because it’s a weak black with a cast to it.
White would be the absence of color.
That chart shows RGB versus CMYK. CMYK is the color printing standard. CMY theoretically covers the spectrum but poor gamut means a dedicated black ink is necessary in practice. You’ll see this in color ink or toner cartridges for computer printers, too.
CMYK is not the same standard that is meant when referring to “Primary Colors” though. Those colors are red, yellow and blue. Always have been, before the advent of computer monitors, before the advent of even color printing presses.
I’m sure this makes it all about as clear as mud to people who aren’t in the trade, but this is accurate.
I think it was Animal Planet that did a story of this bridge, being haunted etc. were not consitered...I don’t remember all that was said but it had something to do with the dogs inability to determine how far down the jump was do to factors like large tree landscaping and perhaps sounds that can come from under a bridge with certain types of winds but most likely visual interference as to how high the bridge really was.... I have seen dogs jump out of moving cars, some just don’t have a lot of smarts.
If they can see a big drop off and they’re near it, most dogs will hit the ground, just lay down and have to be coaxed to move any further. Unless, that is, they know the terrain and are not surprised by it. I grew up at the foot of a mountain with several large cliffs. Went all over them as a kid, with my dogs.
Open up the wall that blocks the visual of the height differential. That’ll stop it, but some dogs will freeze and refuse to cross it at all. If that’s not possible, erect a mesh fence or palings to prevent jumping off.
My thoughts, too. Especially when I read that the bridge has solid stone railings. And knowing of those other instances with the parking ramps and building roof tops... Technically, the actions of the dogs resulted in their own deaths. But unless they bothered with a note, I’m guessing none were intentionally suicidal.
A friend of mine about 3 decades ago would have disagreed. He ran a business providing lighting for theater shows, concerts and the like. That was when I learned the difference. All I knew before then was mixing paint.
Your friend was dealing with luminance which operates under different principals. Generating or projecting light and creating colors by doing so is one thing, making a physical object actually *be* a certain color by reflecting or absorbing light is another.
I saw a book once about mixing paints, and it essentially debunked this notion as a myth. The book had reproductions of various mixing experiments.
The mixture of yellow and blue paint is arguably "green" but it's a very dark and muddy green, and would never be accepted as the green paint supplied in kits along with red, yellow and blue. Anyone who has ever played around with water colors or tempera has experienced this, although one tends to discount ones own experience as somehow flawed in the face of accepted doctrine.
You need to keep in mind that paints consist of a pigment and binder. Pigments come from a multitude of sources running the gamut of animal, vegetable and mineral sources. Many times when you mix them, you're not just getting a mix of pure spectral tones, but you're getting some type of chemical reaction as well, which will make the end result something quite different than a mere combination of the original two colors.
I do quite a bit of miniature painting and manuscript art. Because I try to work in a semi-medieval style, I generally limit my palette to the pigments available at the time; in the greens that is essentially malachite, verdigris and green earth. To get any type of variation, it's imperative that you mix varying degrees of blue and yellow to get any type of range. Take a look at the greens in the "Roland" on my home page...many of those are mixtures of yellows and blues.
1961 is a much cooler number because it reads the same upside down.
