1) GemAgim - maroon, bordeaux red or dark green

These are the colors you remind me of. They just pop into my head when I think of you. Maroon, maybe because it's close to a dark red but also kinda not. I think it just fits. Maybe also, because we talked about this color more often over the last few months.
I think bordeaux red fits you, because I like this color and I like you. But not only because of that of course. You just remind me of red more in general. Maybe because it's the equivalent to green, which is your favorite color, or maybe because you're a fire sign. Fire is red and red is also a hot/warm color and you nearly always say it's too hot. Red is also an active color and it's for people who can get angry more often. Even though that fitted to you more in the past, I still kinda think it fits. Oh and the planet of your sign is Mars, which is also called the red planet. So...it just fits.
The last color that reminds me of you is dark green tho. I know, I went from red to green, which is a big jump but hear me out. Gem, you might know why I took this color in the first place. Yes, because it's your favorite color. But there is more to it. In general green also fits you, because you have a green finger, so many plants and you like plants very much. Also I kinda always have to think of Monsteras when I see dark green and they also remind me of you. So yeah, now that's all I have to say. Think about it.

2) Shinya_Tsukinami - dark cyan, dark khaki or beige

These are the colors that you kinda remind me of. You may ask yourself why I chose these. Well, let's start with dark cyan. It's a mixture between green and a bit more blue and that in darker I'd say. The color itself is pretty, like you. And I really don't know why but when I think of your profil I just have to think of this color. For me Shinya is a dark cyan. Blue can stand for loyality and green for growth. You're loyal and I think you grow day for day - with every new experience.
Dark khaki...well, that's like a dark mixture between yellow and green I'd say. I also like that color. It reminds me of some plants and kiwis. Also I kinda think the color somehow aesthetic and reassuring. The vibe of this color just fits you. I can kinda even imagine you wearing something in this color. Maybe a shirt or socks.
Last but not least - beige. Maybe the most fitting and most "basic" color, which isn't meant rude. I think you'd look good in beige clothes, like a coat or boots in a beige - brownish color. Beige is considered a warm and cozy color and in my opinion that fits you.

3) MienaMeiner - green(formal garden) or hot pink

In the past, all the time when I thought about colors that would fit you, I'd always think of a green and a pinkish type of color.
Let's start with green I'd say. The color can also stand for hope, luck and harmony and you're kind of my hope and my lucky charm. But you also like plants very much, that's why I think green fits even more. You also had greenish hair once, which fit you very well. You just give of this fresh and relaxing vibe of green. And I think green is a color that really fits you, also clothing-wise. After I looked up some green tones, I found this color named formal garden and I think that's really the color I thought of for you.
Now let's come to the hot pink. You may ask yourself now:"Why hot pink?" Yes, I could've chosen a normal pink or even baby pink, which is also a nice color but no. I chose hot pink for a reason. Because your hot...no haha, it's true but that wasn't the reason. The color is just such a bright color and idk why but I think bright colors suit you more. Even some neon tones kinda fit in my opinion. So that's why I picked this color. And also because I could Imagine you wearing stuff in this color. Some (positive) characteristics of pink are that it's considered as friendly, tender, cute, romantic and sensitive and if that doesn't fit you I don't know what does.

4) bunnykattiii - orange, red or dark olive green

It could be that for you I see orange, because you use mostly the orange hearts in texts. But also because you have these orange pants and I just see this color in you. It's a warm, positive and also kinda cozy color - also kinda reminds me of summer and autumn at the same time, so I think it kinda fits.
Red is something I think of, when I think of you, maybe because it's also a warm and vibrant color. For me it stands for that passion you put into dancing, but also writing. And it stands for that fire inside you that never stops burning, because you're such a strong person too. Both orange and red, as colors in fire, are fitting there. Oh and I think red also comes into my mind when I think of you, because I have to think of apples, cherries and strawberries when I think of you. (What an irony to write that when -strawberryyumi ist right under you xD.)
Now let's talk about why dark olive green was my last color choice. I also always had to think of an greenish color, when I thought about (bunny)katti(ii). Don't really ask me why, but it's like that. And the color in my head always was more of a darker green. I looked at a lot of colors and found dark olive green. Look at this color and think about it. I think it kinda matches with your energy and vibe. It also reminds me of the forest and forests are said to be calm, pieceful and relaxing. It's kinda true and I think you give of this energy too. That's it.

5) -strawberryyumi - pink, piquant green or black

So well, let me start right away. For you I see a pink, a regular pink though. Not a lighter one, not a darker one, not a brighter one. Maybe because you're also tender, friendly, sensitive and cute. But also because I just think that this soft color fits you. And to me you kinda seem like a person that likes sweets from time to time.
Piquant green? Maybe because of your new theme, but I think this color fits you in general. You give me hope, luck and the vibes of harmony and growth. You're such a strong person and learn from your mistakes, or at least you seem like you do. Oh and last but not least I kinda see you liking green tea.
Lastly black. Probably the most basic color but rarely picked as a color people see as fitting for someone else. It's not meant anywhere near rude, nothing here is. You just kinda radiate elegance, but you're also quite mysterious. Oh and you can be kinda grim too. That this color is a great color for you to wear probably isn't news to you.

I really don't know what you all say, but you can always comment what you think about that. Do you agree or would you give someone a different color and why?
Oh and do you like this idea or was it rather dumb to make a book about something like that?
Have a great day, take care and stay safe!
