Germany Blue card – 1 Year Rule vs Certificate 51

I joined a German Company dated 01 July 2016. I was sent to Mexico , by my German Company dated 1 April 2018. The project comes to an end and i have to move back to work in the same company to Germany . While exiting Germany , the Foreigners office told me that if I want to keep the Blue card valid , I have to visit Germany every 1 year. Additionally i can also take the Certificate 51. Certificate 51 allows you to leave the country for more than 1 year, keeping your blue card valid.

1)Is there a way to check the validity of the Germany Blue card (Blue card Sticker says 30 June 2020)?
2)I was visiting every year in the meantime . My last travel was for a week to Munich ending 07 June. Based on the 12 month rule. I can still travel till 06th June 2020. Frankfurt Police has confirmed me the same.
3) The certificate 51 expired dated 26 03 2020 . And now Foreigners office says that since you were not back before 26032020, the Blue card has expired. It was not possible to travel because of Covid. I have already given the cancelled tickets to them. The Foreigners office is giving only importance to certificate 51, and not to one year Blue card Rule.

Please help in this case , what is more important 1 year Blue card Expiry Date of Certificate 51 ? Where can I read detailed rules for this ?

Thanks

color scheme – Why are all screens of SpaceX dragon control panel blue themed?

Regarding dark mode:

The researchers found significant thinning of this membrane when participants read text presented in light mode and significant thickening when reading text presented in dark mode. The thinning was more pronounced in participants who already had myopia.

This result seems to suggest that, even though performance in light mode may be better in the short term, there may be a long-term cost associated with it.

However, it may also be borrowed from aviation guidelines. In the following post, there is a discussion regarding white displays affecting night vision.

The FAA guidelines also has a brief section regarding luminance (3.2.3):

Information should be readable over a wide range of ambient illumination under all foreseeable conditions relative to the operating environment.

It’s also hard to say the displays are blue. It might be because of the angle of the photo and the composition of the display itself. There are photos where the interface appears dark grey / black. Additionally, we also don’t know if the interface has other contrast settings to perform in different light environments.

accessibility – Colorblindness-friendly colors called “green”, “blue”, “yellow”, and “red”

I need to choose a palette of four colors that satisfies the following two conditions:

  1. Colorblind people can easily distinguish all four of the colors.
  2. People with normal color vision can unambiguously identify each of my colors with one of the names “green”, “blue”, “yellow”, and “red”.

For context, I’m making a video game version of a board game that uses standard Icehouse pieces. The shape, size, position, and orientation of the pieces are all relevant to gameplay, so I can’t use any of them as a substitute for color. Also, each of the colors are referred to by name in the rules, so using colors that are ambiguous or unrelated to the original colors would be confusing to people familiar with the original board game.

Given the above, what’s my best option?

color – Why are word processors blue and spreadsheet programs green?

I believe that this is just following the idea that the market leader (in this case: Microsoft) had.

There is an interesting article about the history of MS Office software here: http://www.thewindowsclub.com/history-evolution-microsoft-office-software which may explain more.

Originally, teal colour was used in the icons of both MS Word and MS Excel applications. The icons had a different shape, though. At some point (as the article screenshots show: in 1999) the developer decided to use different colours to easier tell one from another.

At that time, due to the obvious market leadership, the applications themselves were equated with their purpose (so instead of saying: “Send me that rich text document!” we used “Send me that Word (file)!” and similarly “spreadsheet” = “Excel (file)” etc.).

What was behind the choice of a specific colour may be hard to identify now, but the sole fact of making them different allowed to make easy connection between the application icon and the file icon, as both of them contained the same elements (namely: the file icon contained the icon of the app opening it). This reduced the cognitive load used to identify the right subset of files in a long list of them (look for green if you want a spreadsheet and blue if you want a text document).

From now on the convention was followed about using green for Excel, dark blue for Word, and other dedicated colours for the rest of the applications in the package. The competitive solutions started following many conventions regarding the UX of the software, compatibility, formats etc. Between them, the colour convention was apparently followed as well.

One more thing regarding the choice of colours is that for the User who, in many cases, was familiar with Excel greens and Word blues, leaving the same convention would, again, limit the cognitive load when moving from one solution to another.

exposure – Picture with blue streak

I am trying to figure out why this picture has this blue streaks in this picture.

I know this is taken as a selfie in a cheap non backed mirror ( it was a hand held and the mirror became unglued from the plastic. ) It’s in my bathroom under my cabinet/cupboard. My plant light is in back.

This is not me but I will include some pictures I took to attempt to recreate the original. I also have somewhat of a glowing blue.
Thank you!

Is there any Germany article number that allows the blue card dependent to stay abroad for more than six months?

My wife is a pregnant (now in 6th month) and she wants to stay in India for almost 10 months (for delivery, visa for baby too), I want to know is there any article number that allows the blue card dependent to stay abroad for more than six months? I asked the Ausländeramt they said it is not allowed for more than six months but I read in many blogs that blue card dependents are allowed maximum of 12 months. I would like to know about an article number that existed that allows to stay abroad for more than six months.
