+Gammy is a GUI tool for adjusting pixel brightness and temperature automatically
+or manually.
+
+It can dim the screen if its content is too bright, or brighten it otherwise.
+This can help your eyes adjust when switching between dark and light windows,
+especially at night or in suboptimal lighting conditions.
