I’ve been playing around with suns for a day and still see a few things wrong, especially the star classes. Here are some examples:
This star is supposed to be class K but it’s class M
This star has a red halo but is orange so it needs to be in class K
This star needs to be in class G because it’s bright yellow
And this star is F class because its yellow color is brighter than the star above
Many other stars have the same situation when I check again. So I have two suggestions, @InterAction_studios, please take a look to make our game even better.
1.1. M-class Star should have shape and color like this: (=< 3700K)


1.2 K-class Star should have shape and color like this: (3700K-5200K)


1.3. G-class Star should have shape and color like this: (5200K-6000K)


1.4. F-class Star should have shape and color like this: (6000-7500K)

1.5. A-class Star should have shape and color like this: (7500K-10000K)

2.Change the color of class B stars and class O stars like this:
2.1. B-class Star(old):

B-class Star(new):

2.2 O-class Star(old):

O-class Star(new):

Here is the spectrum chart, star color and star class I made for everyone’s reference:
The reason I changed the color of the B and O layers: to make them easier to see and distinguish from the old version, I find them quite difficult to distinguish.
Here is the temperature chart for the main classes of stars:

Hope @InterAction_studios accept this idea of mine.
Thank you everyone for reading to the end of this article.
