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?

bugs – Nubia Red Magic 3 shows negative storage on some apps and it’s driving my nuts

Probably a bug but I still want to share exactly what’s going on and hopefully find a solution. I can’t use a logcat for some reason (Sepolicy issue maybe?) But anyways I own a Red Magic 3 and it’s been a trouble from the start. Every once in a while apps crash, and I’m getting negative storage on many applications (not viewing my entire storage but viewing apps individually).

I’m on Android 9 btw.

This leads to many issues. One: If I need to clear an app data for ex. Snapchat, the storage will be negative and it will refuse to let me wipe the storage since it’s in the negative. The “Clear Storage” button is greyed out.

This leads to a bogged down phone, apps don’t run in the background correctly, notification bugs and overall a noticable change in how the phone feels in performance.

Google Play has recently stopped working completely and I believe it’s the storage bug.

Second, the issue can be fixed by, unfortunately, factory resetting my Red Magic 3.

I also noticed that it seems to do this when Magisk is installed which leads me to believe there is a storage bug of some sort.

I’ve search many threads but none that fits the issue I’m looking at.

Any ideas what might be causing it? Could it be a major bug from Nubia?

I seriously regret getting a Nubia smartphone because I’ve heard bad things from the company. Customer support sucks, they take a long time to provide updates. I am trying to fix the logcat issue as of right now.

Are conservatives and red states laughing at their bums because the majority of coronavirus deaths are in blue states?

No, but we're going to keep laughing as red states suffer less economic losses by opening and reactivating their economies and coffers, while blue states are deepening debt and destroying more and more businesses in their state.

His self-imposed liberal ideological death for their states.

I wonder how many deaths from inability to perform cat scans, colonoscopies, x-rays, tumor biopsies, etc. will occur in blue states in the coming months that will not occur in red states because people can get the "unimportant" health care "that saves her life.

nikon – Red noise at the bottom edge and corners

I would like to ask you for your opinion if you have seen a similar red noise in the lower parts of your pictures in your past in low light conditions.

It shows up in the bottom edge and corners. It comes out when this part of the composition is mostly black or dark and there is a low-light setting where I have to increase the ISO slightly.

Example Pictures:

At first I thought I was going too high with ISO (on previous pictures I noticed that ISO was sometimes 1600), but this example image was taken with ISO 640, 18 mm, 1: 3.5, 1/60 sec. On a Nikon D5600 with 18-55 mm kit lens.

/to edit:

I have added a new image that I have processed and in which I noticed unusual noises at the bottom / right edge. Image parameters: ISO 1000, 18 mm, 1: 3.5, 1/20 sec.

Of course I understand that one would normally not increase the exposure so much to generate so much noise, but I did it only to illustrate my noise problem … 🙂 The right side looks like it was from the page burned out very margin, while all other areas seem to have "normal / regular" noise.

/ edit2:
I got in touch with Nikon and there have been some back and forth movements, but the customer service representative seems reluctant to acknowledge that this could be a sensor problem, although by exchanging my 18- I have proven that it cannot be the lens . 55 m kit lens for a fixed 35 mm prime lens with the same results:

Ask:
Does anyone have experience with Nikon customer service? Is it unrealistic to expect them to admit that it's likely a sensor problem? Is there also a chance that they will choose to replace my camera body, or would I have to send it in for examination and possibly try to repair it? I have no past experience, so I'm not sure what to expect. Any advice would be greatly appreciated!

Astrophotography – How do I prevent intense red noise on a deep sky photo?

This is a fragment of my last photo of the wind turbine galaxy (M 101):

M 101 image with strong red noise

As you can see in this enlarged (200%) detail, the picture is full of red noise, which means that all red objects (M 101 has several emission nebulae) literally drown in the noise:
detail

Parameter:

  • Canon EOS 70D (astro-modified)
  • Canon EF 100-400mm f / 4.5-5.6L IS
  • 400 mm
  • ISO 2000
  • f / 5.6
  • 22 2.5 "images
  • 5 dark frames subtracted

During the observation, the sky was clear, the object was near the zenith, and the temperature was +10 ° C (+ 50 ° F).

So what should I do in the future to make my astrophotography quieter? Maybe that's thermal noise? Thanks a lot.
