Scalar value for argument 'color' is not numeric type error in cv2.circle()

[gizemozd]

The following error occurs while generating the video with a stimulus indicator.

~/Desktop/GIT/utils_video/utils_video/utils.py in add_dot(image, radius, center, color)
    589 
    590 def add_dot(image, radius=35, center=(50, 50), color=(255, 0, 0)):
--> 591     image = cv2.circle(image, center, radius, color, -1)
    592     return image
    593 

TypeError: Scalar value for argument 'color' is not numeric

I tried these options but neither worked for me:
color = np.array((255,0,0), dtype=np.uint8)
and
color = tuple([int(x) for x in (255,0,0)])
