In After Effects, the red color in rotation values indicates to the positive rotation. The color convention is used to split between the positive and negative values:
# Red Values: positive rotation values.
# Green Values: negative rotation values.
For instance, a rotation value of "+45°" will appear in red, indicating a positive rotation in a clockwise direction. Conversely, a rotation value of "-45°" will appear in green, indicating a negative rotation in a counterclockwise direction.
When manually adjusting or keyframing rotation, understanding the color-coded representation can help ensure the correct direction of rotation and prevent animation errors
