It was a special day in Ponyville School because the School Fair was open, all the students presenting projects or models and plenty of game and activities to share in family. Apple Bloom basically dragged Applejack around, wanting to play every single one.

"Darlings, you look smashing today!" Rarity said coming over with Sweetie Belle at her side.

"Having fun, Rares?"

"Certainly. The school has put in quite a performance. So many colorful activities. Oh, I do recommend you and Apple Bloom take the free painting stand, you´ll love it!!" Rarity said rubbing her snout against her sister, both covered in paint stains.

"Well I..." Applejack began but she was dragged by her enthusiastic sister and soon the two were making a picture using nothing but their hooves.

"That´s...quite an interesting choice of colours, Applejack." Rarity said, looking at Applejack work. "Twilight could certainly use some green although not in her entire body."

"Thanks, I guess..."

Applejack apologized and left her sister playing with her friends while she went to get her hooves cleaned. Rarity observed the paint attentively until an idea came to her.

"Applejack dear, could you help me with something?" she asked. "I was about to buy these precious earring Silver Spoon made but I wasn´t sure which one will combine with Fluttershy´s blue mane."

"Oh okay...umh that one."

"Are you sure?"

"Su-sure, ah orange goes well with blue right? Right?" but looking at her friend face, Applejack realized the truth. her secret had been exposed, she ran away before being forced to give any explanations.

It was to no good, Rarity had been Applejack friend for years. She find her quite easily.

"Ah, guess I better just said it. Yes Rares, I can´t see colours. Never could."

Rarity sit down next to her. "Well, that certainly answer some questions. Like why you never place green apples and red apples in separate baskets. That always disturbed me."

"You were the only one disturbed by that. I usually can hide it but you have to be so damn attentive to details!"

"..."

"Sorry, didn´t mean to yell at you. It´s just...I hate this. I hate not being able to enjoy the world like you do."

"Whatever do you mean?"

"You know how Pinkie is always talking about colorful this and colorful that, and Fluttershy is always talking about birds and their feather colours; I always just nod along but I really can´t follow. They all seem alike to me. I can´t even see Rainbow´s tricks, they all look that sick kind of green, I guess. Heh, it is funny. I heard ponies saying that out of six of us, I´m the least special. Guess that´s the reason. I can´t see the world in nothing but those dull colours because I´m dull mysle-AUH!"

"Don´t you ever say that again!"

"Auh! Say it, don´t slap me...”

Rarity apologized and continued. "You´re one of themostt special ponies I´ve met Applejack. You´re brave and loyal and kind and always honest..."

"Not that honest, I´ve been keeping this from you for years."

"Yes, a mistake on your part. And mine too. I can´t tell who was the blind one, me for not realizing sooner; or you, for failing to see all your good qualities."

Applejack was shrinking more and more in shame.

"I actually envy you."

Applejack looked back at Rarity, asking silently "what?"

"I see the world just like anypony else, all the same colours. But you see something unique. Oh, I would love to see my dresses devoid of colours. Wonder how could I combine just dull tones maybe a match of black and white, OH idea!! pearls and onyx!!! Brilliant!"

Rarity was already lost in her own world of fashion and design. Applejack looked over at the school, filled with all sort of colorfoul colt and fillies, but throught Applejack eyes they seemed a dull kind of sepia. Despite of that she was able to spot her sister, laughing along her friends.

She may not see her in the bright red and yellow that everypony else does; but she was able to see the lovely filly that she called her sister.
