Error "unknown named color"

Description of the problem:

Dear all,

I am trying to debug my online study. One of my problems is:

On pavlovia I receive the following error: “when defining color -> unknown named color [1.000, 0.004, 1.000]”. I want to show a bi-colored pixel square with three loops and changing color pairs during every loop. I can not find this color in my JS or my xlsx files

I am glad about every helpfull suggestion.

Best regards,
Vinzenz

I had a problem with color from the Javascript end, and I was fortunate to receive some very helpful advice from another user. Here’s the link to the comment, see if that works.

Changing line colour with mouseover [Javascript]

Ah – I’ve spotted the issue. I had a problem with colours which I’ve solved by defining them at the start of the experiment. e.g. Begin Experiment Python - red=[1,-1,-1] Javascript - red = new util.Color([1, -1, -1]); Then use red without quotes in your code. This is in my crib sheet. Best wishes, Wakefield

Unfortunately this does not seem to solve my problem. I tried to adapt it, but I stille get the following message:

` Unfortunately we encountered the following error:

when defining a color
unknown named color: [0.0, -1.0, -1.0]

Try to run the experiment again. If the error persists, contact the experiment designer.`

Does it maybe have to do with an undefinded color space (I want to use rgb)?

[Vinzenz]

Is it possible to use decimal numbers for the color space? Could that be the problem?

This is how I have defined colors from the Builder View using the code component:

I’m not too sure about decimals.

Hi Vinzenz, did you solve the problem with the colors? I have the same problem.
