So these hashtags were posted by BW.
Many people, including myself have been wondering what those words/symbols mean.

Since I had nothing to do. I tried to imagine things, search online, and then arrange this thread.

And I was a bit surprised and all smiling

I start with the MOON. .
In some 2 of these pics, there's also cosmic CLOUD.

Then, last night's Bright's meow just remind me of a particular CAT who has association with moon.

So yeah, I wondered, that must be it.
LUNA
--> Goddess of The Moon

Then I look into it further.
Look what I found!

This beautiful deck of playing cards has moon, and also sun symbols.

And the description suitably describes BrightWin.

The Joker, though! LOOK!
As you may noticed, I highlighted one specific color!

And that violet. But which violet?

Funny coincidence? That the 4th picture has moon in it? tbch, I don't know, but I like it.

Many would think the fandom color is B/W, myself included.
Because B/W = BW = Bright Win

But we all been deceived.

It's Metalic Violet = MV = Metawin Vachirawit.

This was how far my mind wondered and wandered.

And for sun-moon correlation:

Wait? What? There's also mentions about darkness and light?
The highlighted parts match with BrightWin.

For more thorough elaboration, you guys can read this site.

PS.
There's mention of cosmos.

BrightWin is inseparable.

And everyday of our lives, we'll see the cosmic/cosmo/cosmos both in literal and conceptual meanings.

PS.
"You can't have one without the other" can also mean, can not exist without fans.

Let's talk about Sun-Moon relation once more. And I mean what symbol commonly used.

Regarding BW, the sun represent the REBIRTH of Bright as an actor and of Win as he just "switched" to more focus on pursuing his dream/passion in entertainment industry.

The sun also represent the strength and power BW bring not only to each other but also to fans, and to the same sex communities around the world.
While the moon is a symbol of nurturing, protective, and unconditional love from within and around BW.

With all being said, I think I can comfortably say that:

1. Our fandom name will be: Cosmic/Cosmo/Cosmos
2. Us fans will be called:
Luna
3. The official fandom color will be: Metalic Violet
4. The symbol of the fandom will be: Sun-Moon.
Something like this.

That's all from me.
Whether is wrong or right, only time will tell.

If the fandom name is Cosmic/Luna, through, not gonna lie, I'd be happy af!

Peace out!
