Ubuntu has a pinky orangey hue

Ubuntu screen gone pink


There is an orangey pinky hue to the Ubuntu desktop.


To prove it's a software problem, reboot the computer and the BIOS/GrubLlogin screen will all look normal. The correct level of colour is present, and things only go pink after you have logged in.

With a software problem, the fault only appears after you have logged in and does not appear in the BIOS boot screen or grub menu.


Now for the pinky, orangey or even rose-tinted Ubuntu desktop fix.

Navigate to the settings and search for 'Night Light'.

Switch the night light option to OFF (grey button showing) from the ON (blue button showing).

Your screen should now return to its proper colours and the pinky, orange hue disappears.

Rose Tinted

Different displays can render the colour slightly differently, it could have an orange hue or a pink hue. The brightness slider still changes the brightness but it doesn't get to the full (100%) brightness than with the Night Light off. Tilting the laptop gave different shades and intensity of the colored tint and it took a while to work out what was happening.


Someone had set the 'night light' to come on at a pre-set time of day, altering the colour temperature of the screen to reduce the blue and increase the warmer colours.


An amber light on the computer screen, often referred to as "night mode" or "blue light filter," is used in the evenings for several reasons:

1. Reducing Eye Strain

  • Less Blue Light: Amber light reduces the amount of blue light emitted by the screen. Blue light can cause eye strain, especially during prolonged use.
  • Comfortable Viewing: The warmer tones of amber light are easier on the eyes in low-light environments, making screen time more comfortable.

2. Improving Sleep Quality

  • Circadian Rhythms: Blue light can disrupt the body's natural circadian rhythms by suppressing the production of melatonin, a hormone that regulates sleep. Using amber light helps maintain natural sleep cycles.
  • Better Sleep: By reducing blue light exposure in the evenings, it becomes easier to fall asleep and maintain a healthy sleep pattern.

3. Enhancing Visual Comfort

  • Reduced Glare: Amber light can reduce glare from the screen, which is particularly beneficial in dim lighting conditions.
  • Eye Relaxation: The warmer hues are less jarring than the bright, cool tones of blue light, allowing for a more relaxed viewing experience.

4. Preventing Digital Eye Fatigue

  • Minimized Digital Eye Strain: Prolonged exposure to blue light from screens can lead to digital eye fatigue, characterized by dryness, irritation, and difficulty focusing. Amber light helps mitigate these symptoms.
  • Longer Comfortable Use: With reduced strain, users can comfortably spend more time on their devices without experiencing significant discomfort.

5. Healthier Computer Use Habits

  • Encourages Breaks: The subtle shift to warmer tones can remind users to take regular breaks, promoting healthier computer use habits.
  • Overall Well-being: Reducing blue light exposure not only aids in eye health but also contributes to overall well-being by supporting better sleep and reducing stress on the eyes.

In summary, using an amber light on the computer screen in the evenings helps reduce eye strain, improve sleep quality, enhance visual comfort, prevent digital eye fatigue, and promote healthier computer use habits.


Maybe it seemed like a good idea at the time but it was very distracting while making the viewing angle very tight on the old laptop screen.
