Are there any wire-color standards for SPI?
Well SPI is usually used between components on the same board.
I have never heard talking about wires and color concerning SPI.
It is well known that clock signals will only travel over orange coloured wires.

I'm bread-boarding an ICSP connection with individual wires.

No big deal. For someone like me (more ambition than experience), it makes wiring and creating cables a bit easier.

Got it! Orange for clock. ;D

Oddly enough, I tend to use orange for clock signals :O.
But, I too don't know of any standards. Perhaps it's best to choose some colors, write them down, then stick to it?

Well it is odd because I made it up. Mind you it wasn't a random choice. Given that red is a supply, in this case of power, then a clock is also a supply in this case of timing signals. So it seemed logical to chose a colour that was close to red - hence orange.
My wife's explanation...
Even Stanley Kubrick thinks it's a good idea...
A Clock Works on Orange
I never really thought about it that way, Mike, but that makes sense. I guess I subconsciously thought that (or just randomly picked a color :)) and stuck with it ;D.

;D!
I was just thinking about that the other day - in regard to jumper wire colors.
I always use yellow for the clock (didn't have orange until I bought some cheap-o jumpers) and I use blue for data (I2c).
For serial I use green for xmit and blue for rcve.
It may sound silly or pedantic but often saves me time - and the effort to put on my glasses.
My goal is to make color-coded cheat-sheets with matching wire colors so I can quickly and accurately setup a breadboard.
I went with this scheme...
VDD - red - because it's connected to VCC
GND - black - who wouldn't use black for ground?
Reset - blue - because it "freezes" the processor
(U)SCK - orange - because clocks work on orange
MOSI - green - I've often used green / yellow for communications (usually RS232) transmit / receive
MISO - yellow - see above
I redrew this in AutoSketch and added the color bands. With a similar picture for the ATtiny84, I'm one happy guy!
Yesterday, for the first time ever, I tried using lead-free solder. It went surprisingly well. I made about the same number of mistakes I usually make and was able to correct the mistakes. The joints conduct electricity, are fairly smooth and shiny, and seem to be strong.
GND - black - who wouldn't use black for ground?
Well me, ground or as we say in England Earth is always green given the choice. That way you can have black for the negative supply.

Dang. I like that.
Unfortunately, it doesn't fit with the battery cages and USB cables sold here. The power wires are always red and black. I want the colors to match to reduce the chance of a mistake.
Black "is" negative,
white "is" neutral,
Green "is" ground.
negative, neutral, and ground are 3 very different things to an electrician....
It seems there is no "real" color standard - the above comes about as close as anything for electrical (not neccessay electronic) here in USA.
I like Orange for the clock signal.= <:)
