color in filelog is in a mess

[RonaldinhoL]

i guess we should split the filelogger to use another formatter that not use color, or it will be a mess.

�[36m[D 210715 10:47:45 main:20]�[39m hello world
�[36m[D 210715 10:47:58 main:20]�[39m hello world
�[36m[D 210715 10:47:59 main:20]�[39m hello world

now i use two logger instance, one for color console output, one for file log, maybe there is another more graceful solution.
