I need help here please....

hello friend, To turn red into black color...you should combine yellow and blue dye mixture(check for the best dye brand)you bring it to a boil(the yellow and blue dye powder) before putting the t-shirt on... Yellow + blue+ red = black...hope you can make it.

What a bummer Rajaiv! I think that black may cover anything! It's worth a try. I would go online to about.com and see if they have any specific info on dying over a color. I know when you are doing hair, depositing color on top of color is usually a no no. Except for black. Black will color over anything. In any case, what we do if they're is color is to remove it by bleaching it. If you want you could bleach them first. I dont really think you have to. I would just go ahead and dye them black and leave them in for as long as you can. dl

I have tried to search online how you can dye your red tshirts to black colour. I don't know if it is some kind of joke or not. I seriously think that it would be cheaper to buy new black shirts instead of trying to dye them :)

you need to check the label on the shirt to see what they're made of. if its cotton then it should be ok. but it will be expensive to buy that much dye and salt. i would chuck them in the bathtub in small batches. each dye pack does about 2 shirts i think so you're gonna need an AWFUL lot of dye! and i think you have to use twice as much for black. if the label says polycotton (or a mixture of polyester and cotton) then you'll never get it black just maroon. you could try fabric paint? or if you only have to wear them once pnting them with ordinary wall paint?

I did this once when I was a teenager and it was a lot of fun... Here is a website that gives you the how tos, step by step, and what dye to use... A suggestion... Since you have a lot of shirts to do, and it sounds like a big job, you may find it fun to have a day of it with the kids on your team.. I am not sure where you live, but if its like here where the weather is finally starting to get warm this would be a cool activity for them to do... Also less stress on you personally.. Ya their hands may get multi colored, but it will wash out sooner or later.. http://familycrafts.about.com/cs/tiedye/a/041601a.htm Hope this helps, and its a lot of fun, just can be mess Good luck

First make sure that the shirts are all cotton. If they are not you may have some issues with the cloth accepting the dye. Then go and purchase RIT dye. It is specifically designed for dying clothes. Mix according to the package you purchase. Test dye one shirt before doing so to the entire group. To dye soak the shirt in the dye, there should be a recommended time for color to set on the package. Then wash to remove any excess dye. Since the shirts are already red, I don't know if the color will take as well.
