Color constant to/from string?

vinicity

Hi!

Just a quick question:

Is there a way to get the name (as a string) of a particular color constant?
And the other way around, can you go from a string color name to the corresponding constant?

I could not find anything in the help about this...

xevdev

Print(red)
Will show you the vector rgba
Red 1.000
Green 0.000
Blue 0.000
Alpha 1.000 transparency
I don't think you can go the other way unless you made your own list and put it in a function

vinicity

Thanks.

I was more looking for something like

Print(convertToStr(red))

which would give me the output:
red

and then something like

Print(convertToColor("red"))

which would output something like:
1.0000, 0.0000, 0.0000, 0.0000

(...that is the color rgba vector for red).

xevdev

How many colors ?

pianofire

@vinicity I don't think there is a way currently. Leave it with me and I'll see if I can do a user function

xevdev

You might run into trouble just looked at the color section and thought
Maroon
Darkred
And burgundy looked pretty similar
Tried all three and burgundy doesn't exist
It looks like they've named about a hundred colors out of a possible (2 to the power 24)

pianofire

Yes this will only work for colo(u)rs with defined constants. I think burgundy was a typo it is in as burgandy

xevdev

Burgandy doesn't work either

pianofire

It is not syntax highlighting but it is displaying OK:

loop
  clear(burgandy)
  update()
repeat

@vinicity Here you go try this: https://fuzearena.com/forum/topic/957/functions-to-convert-from-a-string-to-a-colour-constant-and-vice-versa

Let me know if you find any problems

@pianofire Thanks a lot! Exactly what I needed!
