Just coat yellow cotton tape with amber shellac. It looks similar (a bit better if you ax me), you can get it to match a Brooks, and it's way more durable and cheaper. And it won't turn into rotten zombie flesh.
I use shellaced yellow hockey tape on my bike. Alone hockey tape is terrible, but with shellac over top it's beautiful and it has a mindboggling functionality to cheapness ratio. It's literally 70 times cheaper than brooks tape.
