Pokémon is such a great series, and I had the pleasure of being just the right age when it first came over to the States. Even after all these years, it's still going strong. It's been refined and tweaked over the years so that it still manages to stay fresh. My favorite will always be my first, though. I know a lot of people around my age who were there at the beginning regard Red and Blue Version very highly. Vocabulary, locations, individuals, statistics, and the Pokémon themselves spring instantly to mind when the topic comes up. It really has stood the test of time (although a literal mountain of marketing doesn't hurt either).
For colorizing the sprites, I looked a lot at existing efforts done by others, as well as the badges from the anime. The end result was a hybrid of all of them.
It's interesting to note that even though the pixel size seems obvious, the perceived pixels are misleading. They're actually composed of four smaller ones. Certain badges give this away by having very thin columns or rows. When the issue arose during the project, it initially presented a dilemma. I ended up adjusting certain sprites entirely to make them more manageable, although two of them still retain their original dimensions.
Each canvas measures 8" x 8". I found it interesting that the Japanese names for the badges are extremely exciting things such as: Gray Badge, Pink Badge, and Green Badge. The fact that the badge names are written in katakana makes it make sense, though. And it only really applies to Generation I.
The Mega Man-esque background has become my new favorite. It really seems to fit with almost everything. And since all of these projects go to different people, it doesn't bother me in the slightest.
I also just realized that I missed eight pixels on the Volcano Badge, so I should probably touch that up before sending it out.
