The one difference that works the opposite way round is the

Unless you pronounce it gay oll, the spelling is absurd.

Human cone cells come in three wavelengths, roughly r-g-b, so if we
name more colors it\'s arbitrary.

https://en.wikipedia.org/wiki/Cone_cell

 From the diagram on the right, it\'s more like blue, greeny-yellow and
yellow if you measure the sensitivities at different frequencies.

I call bullshit.  If the lowest frequency detector was yellow, how do we
see red?  And why does the RGB system on TVs work so well?

(a) The frequencies represent the peaks of the curves. You will see from
the diagram that both of the yellow sensitive cones have tails that
extend well into the red. We see red by comparing the relative levels of
the two. People with only one type of yellow cone can\'t do this, which
is why they can\'t tell red from green.

Look at this graph:
https://www.ncbi.nlm.nih.gov/books/NBK11059/figure/A766/?report=objectonly

Look at the bright red.  It\'s off the scale for even the 559nm cone.
Yet red is easy to see and very vivid.  The graph is obviously wrong, if
the graph was correct, we shouldn\'t be able to pick up red much at all.

We discern red by comparing the relative stimulation of the three cones.

Think about what colours on that graph are the most prominent.  I see
5.  Purple, blue, green, yellow, red.  So I\'d say either:

(Most people would say violet, but there isn\'t much difference.)

So what about orange? Don\'t you see orange? (People used not to have a
word for it before the fruit was imported.)

Note that I said \"discern\" above, not \"see\". There are tests involving
putting coloured tiles in order (online versions are available); most
people can *distinguish\" between 30 and 40 different colours. Clearly we
don\'t have 30 different kinds of cone.

As well as distinguishing colours in a test, there is the question of
how many spectral colours we regard as distinct. This is a subjective
matter, dependant on culture, occupation and whether we have names for
the colours. For example, I can see that orange is a bit reddish and a
bit yellowish, but (to me) it has a distinct quality of orangeyness.

I\'ve tried, but I can\'t honestly see indigo as a distinct colour; it\'s
more like an intermediate between violet and blue. (We are only taught
that indigo is a colour of the spectrum thanks to Newton and his liking
for the number seven.)

We have 5 cones, purple, blue, green, yellow, red - but I\'m sure doctors
would notice we had 5.

We have 3 cones, purple, green, red.  The 5 vivid colours I mentioned
above are when we either see it mostly with one cone, or equally with 2
cones.

Having cones where the graph shows them doesn\'t make any sense.

It does fit in with our knowledge of how colour vision likely evolved in
us and other primates. Other mammals have just two kinds of cones: blue
and yellow and effectively have red/green colour-blindness. The gene for
the yellow cone could have duplicated and one copy mutated so that it
responded to a slightly different wavelength of light. This was perhaps
useful in our ancestors at it would enable us to distinguish red fruit
from green leaves, or ripe from unripe fruit.

The retention of red/green colour-blindness in some people could be
because such distinctions aren\'t all that important, or it could be that
such colour-blindness defeats the camouflage that some predators adopted.

Oddly red+green light produced yellow. At least it seems odd to me, but
I can\'t get into others\' heads. Yellow looks completely different from

a light blue to me, but maybe if it is darker it would look teal, which
is blue-green.

Your brain presumably just thinks up what they should all look like.
The only one that seems weird is red and blue making something similar
to indigo/violet, which is the other side of blue to red in the
spectrum.  Looking at ultraviolet is weird.  They claim we can\'t see it,
but I can feel it.  Maybe I\'m feeling it burning my eyes.

It\'s odd that colour circle (wheel) diagrams look right, and violet
looks like an intermediate between red and blue. Is this a perceptual
matter, or is it that extreme red is twice the wavelength of extreme
blue, in which case it\'s physical? If so, why should this be the case as
our eyes are just adapted to the range of light mostly produced by our
Sun?

The sun produces violet and ultraviolet, so why are you confused?

Your preceding paragraph would indicate that you too think it\'s odd that
violet appears to be between blue and red; opposite ends of the spectrum.

My parrots can see UV clearly, I have UV bulbs because apparently it
makes their feather colours look better to their eyes, so they\'re
happier and more randy.

Parrots and ultraviolet are irrelevant as we can\'t see ultraviolet.

isolation between the clients.

Look. Every LNB can be tuned to a different MUX or polarisation. They
are smart, not dumb head amps. LF or DC Signals go to them down the coax
to tell them waht to do.

You need one per active watching session and one per active recording
session unless you are recording of the same Mux you happen to be watching
In general two or more cables from tow or more LNBs will feed a set top
box and recorder.

4 LNB dishes are very common

The point is that they are not at the same voltage. ,

Sounds like a good way to annoy a neighbour you hate and prevent them
listening to the radio station you don\'t like.

People got used to hearing squeals in the early evening when people were
tuning their radios in. Just as, later, people listening on long wave
got used to the whistling interference from 405 line TVs.

How come I remember a whine on LW and I was born in 1975?

Two things happened around those times.
405 was 10.125kHz. 625 timebase is 15.625kHz.
Droitwich moved from 200kHz to 198kHz.
Also, there would have been a lot of 405 sets still around.
I\'ll let you check whether a whistle was possible.

Er.... LW is 150 to 270 kHz, nothing like 10.125kHz or 15.625kHz.

Droitwich is either a spa or a transmitter which would have transmitted all frequencies used, not just 200 or 198kHz.

Your point?

In Spain there are conventions on that. Hot is left. But German taps
(Grohe brand) assume hot is right. They all turn in the same
direction,
although modern ones do not have any screw thread.

So when we installed a Grohe on the kitchen, we reversed the
tubes. Hot
is left, but red colour.

But red?! Hot IS red.

That\'s just a convention. And blue is cold. Sometimes cold is green
instead; why\'s that? Maybe green should be hot and red cold, as I think
green chillies are \"hotter\" than red.

It\'s the colour of your skin at different temperatures. They could have
gone by the colour of metal (blue is hotter), but that would be less
understood by the masses.

No metal can stand the temperature needed to go blue (>10,000K).

Is white or blue hottest? Filament lamps go white. Presumably if it
starts with red, as you heat it up you get blue aswell, then eventually
lose the red?

As you heat something, it produces radiation more or less independent of
what it is made of. Initially all the radiation is in the infrared, so
we can\'t see it. Then it creeps into the red end of the visible spectrum
and looks dull red, then bright red, then orange; when the \"hump\" of
radiation is mostly in the visible spectrum it looks white to us. This
is at 6000K which is the temperature of the surface of our Sun, to which
our eyes are adapted. If you go on raising the temperature the hump
moves out of the violet end and the light looks bluish as it has lost
the red. This is why the star Sirius looks bluish, as its surface is 10000K.

Filament lamps are rather yellowish, as tungsten tends to evaporate much
above 3000K; less for halogen lamps which can stand a higher temperature.

Ah, that\'s why I like 6000K LED lights. And before that the rather rare and expensive 6000K CFL lights. Although I now add UV since my parrots can see UV. You\'re supposed to buy very expensive lights which include UV. I just use normal ones and add cheap UV LEDs intended for discos.

I\'m sure you could get blue metal in a vacuum.

So why is it sometimes green for cold? My skin is never green, as I
don\'t photosynthesise.

What if you caught gangreen?

I think gangrenous tissue is black, not green.

Then why isn\'t it called ganblack?
