Fuse with colour band ?

I pick up one fuse from the floor,the fuse was 5x20mm miniature
fuse without any written rateing except colour band print on the glass
suface Blue,Red, Black,Yellow. I'm curious to know, should I read from
the Blue or Yellow band as both end are symmetrical.Does
any person know the value of the fuse ? Thanks !
