Tell me your favorite color coordination's.

I've always liked orange and white because it'sthey're the colors of my favorite videogame character's color,s, "Ratchet and Crlank".

I've found recently that orange color more facilitates communication with color effects.

I will be honest, this sentence is difficult to understand

Unfortunately there are less people who like orange as a color.

Tell me your favorite color coordmbination.

For US English: "color combination" would be the most natural. Color palette and color scheme are more typically used with design, such as a room (kitchen, bedroom, what colors to use on the walls, furniture...etc). Or designing a website. Color coordination is more about matching things. This even could be color coordinated clothes. One might first choose a color palette and from there coordinate the colors to match the decor of the room or website.

I've always liked orange and white because it'sthey are the color of my favorite game character's color,s, "Ratchet and Crank"."

In this case I would put the period inside the parenthesis marks.

I found recently found out that orange color mores facilitates better communication with color effects.

Not sure if this is what you wanted to say. "communicating with color effects" is unclear by itself. People communicate with each other but colors do not. Were you trying to say this: "I recently found out that the color orange affects better communication."

Unfortunately, there are lessnot many people who like orangthe color orange.

More natural to say "Unfortunately, there are not many people who like orange."

Tell me your favorite color coordmbination.

I've always liked orange and white because it'sthey're the colors of my favorite game character's color," in the game Ratchet and Crlank".

I found recently learned that orangthe color morange facilitates communication with color effects, according to color psychology.

I'm not certain if "color psychology" is exactly what you're referring to, but this sentence structure works better.

Unfortunately, there are lessfewer people who like orangthe color orange.

"Fewer" is for countable nouns and "less" is for uncountable nouns. Since you can count people, you would use "fewer" here. This is a mistake you'll see a lot of native English speakers make because not everyone is aware of the distinction.

Tell me your favorite color coordinationscheme.

The phrase you're looking for here is "color scheme" or "color palette".

I've always liked orange and white because it's the color scheme of my favorite (video) game character's color,"s, Ratchet and Crank".

(1) When "orange and white" is singular, it refers to the colour scheme. When it refers to the individual colours, it is plural as there is more than one colour. Hence, alternatively, you can also write: "I've always liked orange and white because they're the colors of my favorite video game characters".

(2) Notice that in your original sentence, "Ratchet and Crank" would immediately follow "color scheme", so the implication is that "Ratchet and Crank" refers not to the characters, but to the colour scheme. I have reordered your sentence so that "my favorite video game characters" appears right before "Ratchet and Crank" instead.

(3) Ratchet and Crank are two characters, so "character" should be plural.
(4) We generally do not use quotation marks around the names of people or characters.

I found recently that orangthe color moreange better facilitates communication with color effects more.

(1) Here, "the color orange" is more appropriate than "the orange color". The former places emphasis on the colour orange itself, while the latter emphasises the colour which just happens to be orange, such as in the phrase "the orange color of the wall". I hope that makes some sense.

(2) The placement of "more" is a little awkward. You can use "better" instead. Alternatively, you can also place "more" or "better" at the end: "I found recently that the color orange facilitates communication with color effects more/better."

(3) Here, by "communication with color effects", are you referring to visibility, as in the colour orange is easy to spot? If so, this is how I might personally have phrased it: "I found recently that the color orange is more effective for communication via colors (thanks to its high visibility)." It might be clearer this way.

Unfortunately there are less people who like orangthe color orange.
