As a very young kid at Sunday School I had a very posh lady, with a very upper class English accent as our group leader.
We sang 'All things bright and beautiful' and when we got to the line "He made their glowing colors" I heard her sing 'carlers' for colors'
For a long time after I used the word 'carlers' as correct pronunciation.
Now, being a good old East London boy, I use the correct pronunciation 'kulers!'
