like your idea. :)

yeah i still like this idea
there where several threads about this and i still would like to dye
only thing atm are linnen capes and shields which can be of different colors/designs

i would like to see colored capes of all kinds
or so called "transmogrifications"
or even cooler both could think of great looking mixed styles

And, this exists, but only for specific items, so it shouldn't be too hard to add it in for more things.

you can have a yellow cape, but it doesn't do anything but look nice, see linen capes {red, blue, green, *yellow*, white, black}

Yellow capes exist. Linen capes come in a variety of colors. Were you looking for yellow versions of like troll capes?
