Processing images on an uncalibrated screen in varying levels of luminosity and color temperature will result in inconsistencies. This is a given. If the processing is done outdoors on a glossy screen problems get worse. When ever possible one should process images in low light with the ambient light color controlled and with no bright colored objects in ones peripheral vision. No sunlight should be admitted into the work area as it varies all day long. Even an off white wall behind the monitor should be avoided. When in the field you do the best you can and hope the results are acceptable. I'm sure one can find better advice than mine for setting up a proper work area for image processing on the net. I hope this is a good start.
I ware a baseball cap so the light above my monitor is not in my peripheral vision. A hood over ones monitor can be helpful to keep light from spilling onto the monitor. Again check the net to find good and complete instructions on setting up a work area environment for image processing.
For insight into color perception I suggest reading a small book,
Itten The Elements of Color with a forward by Faber Birren.

I agree that a number of the images in the blog less than optimal. I'm typing outdoors on a small glossy screen so I'm sure my writing is inconsistent.
