True Tone can somewhat affect color accuracy, but it's not a significant difference. It makes your Mac's screen colors appear slightly warmer or cooler depending on the lighting in your environment, leading to a more natural view. However, True Tone is not ideal for tasks that require precise color accuracy, like when using a video or photo editing app. It's best to disable True Tone for tasks like these. You can also calibrate your Mac's display to take color accuracy to the next level.
