I've seen this idea done a few times before with other couples from different shows bd books so bought I would have a go. Just a short one shot.

Let me know what you think.

Everyone knew that you only saw the world in colour when you found your soul mate.

For Sheldon he has always seen the world in black and white. The only love he ever had was for science. He didn't believe there was anyone for him so he never searched.

Some people made it their life mission to search for their soul mate while others simply waited for them to appear in their life just like date wanted.

Leonard saw colour the day Penny moved into 4B, Howard saw colour when he met Bernadette.

For Sheldon and Raj they are still yet to see the bright colours the world offers.

Raj is a searcher. He spends so many hours walking the streets, sitting in cafés trying to find his soul mate but still he had yet to find her or even him. He never gives up hope even when he hears stories of soul mates not finding each other until they are near death and in rare cases not at all.

Sheldon, well he's Sheldon. He doesn't care for sharing his life with someone. He doesn't believe fate will bring him to the perfect women. For all he knew his soul mate could be a dumb waitress like Penny and why would he want to spend his life with someone who couldn't string a proper sentence together.

When Raj and Howard set him up on a soul mate search he was annoyed and instantly refused but after being blackmailed with a dirty sock from the roof he agreed to meet the only women that seemed to be his match.

The chances of her being his soul mate and him actually wanting her was slim.

The day he arrived at the coffee shop his expectations where low. The soul mate matches were hokum in his opinion.

When a voice sounded behind him something changed.

"Excuse me. I'm Amy Farrah Fowler. You're Sheldon Cooper."

When he turned to the sound of the women's voice and looked deeply into her green eyes the world around him began to change.

Colours appeared but only dimly neither of them believed.

"Hello, Amy Farrah Fowler. I'm sorry to inform you that you have been taken in by unsupportable mathematics designed to prey on the gullible and the lonely. Additionally, I'm being blackmailed with a hidden dirty sock." He replied in his usual manor.

"If that was slang, I'm unfamiliar with it. If it was literal, I share your aversion to soiled hosiery. In any case, I'm here because my mother and I have agreed that I will search for my soul mate at least once a year."

He raised an eyebrow at the intriguing women. She was different, good different. The colours around him began to get brighter and from the small smile that tugged on her lips he knew hers were too but her smile soon vanished once again and she went back to keeping a straight face and the colours faded ever so slightly for her.

"My mother and I have the same agreement about church." He said unsure if he should mention the colours and changes.

"I don't object to the concept of a deity, but I'm baffled by the notion of one that takes attendance."

He inwardly smiled.

"Well, then you might want to avoid East Texas." He nodded.

She nodded along. "Noted. Now, before this goes any further, you should know that all forms of physical contact up to and including coitus are off the table."

And once again the colours brightened. Just like him physical contact was not something she desired. Maybe this was a good match after all.

"May I buy you a beverage?" He asked.

"Tepid water, please." She replied.

Although the colours didn't brighten completely for a long time they both knew that day they were soul mates.

Together the colours brightened once the couple began to believe now they live in a world full of the brightest colours.
