  Never mind, if I change the RGB values to Hex values it works.

  Hi,

  For future reference: your problem probably occurred with self coded RGB-guns between 0 and 255, right? PsychoPy uses RGB guns with values between -1 and 1. So PyGame (255,0,0) would be PsychoPy (1,-1,-1), as PyGame (128,128,128) would be PsychoPy (0,0,0).

  Using hex values is a good solution, since your bypassing the gun value difference.

  Hi Dirk,

  The issue is as Edwin says. However, OpenSesame would ideally handle this color conversion for you, so you can switch from one back-end to another without having to worry about the correct color notation. Would you mind sharing your code so that I can take a look at where this goes wrong?

  Cheers,
  Sebastiaan

  Hi dirk.
  I'm an undergraduate student.

  I also wanted to view your color-wheel codes using PsychoPy. Actually, I am trynna make continuous-wheel based experiment but have no idea with how can I calculate the response error in each trial with random condition.

  Can you share your code so that novices can study with it?

  hi,
  could you please share you "color-wheel" code.
  it will save me time
