It 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, to be + portable and to have get accuracy, which + means that you cannot any use 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. + + - No support of ICC profiles. + +Blueshift is not user friendly and it is not +meant too be. Blueshift does offer limited +use of command line options to apply settings, +but it is really meant for you to have configuration +files (written in Python 3) where all the policies +are implemented, Blueshift is only meant to provide +the mechanism for modifying the colour curves. +Blueshift neither provides any means of automatically +getting your geographical position; the intention is +that you should implement that in the policy yourself +using library which can do that. Additionally +Blueshift provides not safe guards from making your +screen unreadable or otherwise miscoloured; and +Blueshift will never, officially, add support +specifically for any proprietary operating system. +Blueshift is fully extensible so it is possible to +make extensions that make it usable under unsupported +systems, the base code is written in Python 3 without +calls to any system dependent functions. +If Blueshift does not work for you for any of these +reasons, you should take a look at Redshift. + |
