+Blueshift adjusts the colour temperature of your
+monitor according to brightness outside to reduce
+eye strain and make it easier to fall asleep when
+going to bed. If can also be used to increase the
+colour temperature and make the monitor bluer,
+this helps you focus on your work.
+
+Blueshift is inspired by Redshift but is vastly
+more flexible and solves some problems with Redshift:
+
+    - Decreases the colour temperature too early
+      during the winter which can make you tired
+      during daytime.
+
+    - Limited support for settings such as
+      brightness and contrast. Technologies like
+      Blueshift and Redshift needs to remove
+      all settings made by other programs which
+      means that you cannot any other program
+      at the same time. Redshift supports only
+      gamman and a limited brightness range.
+      Blueshift can be extended by the user to
+      do anything and have built in support for
+      unlimited brightness, contrast, gamma
+      correction and S-curve correction.
+      Brightness and contrast are normally not
+      important because you should configure
+      that on the monitors control panel. But
+      one may want to temporarly so a change
+      to contrast to increase the brightness
+      beyond 100 %. Blueshift is to might
+      knowledge the first program to support
+      S-curve correction which is important
+      for LCD monitors which suffers the effects
+      of S-curves.
