Yeah, I been there before too, so I know how you feel.
For Light Brown Color:
Well, if you buy a regular Hair Dye Kit from the supermarket, it usually do not include a bleach chemical. This mean, your black hair will turn only a little bit to brown, and your brown will turn into a lighter brown. If you want a light brown, you must do a bleach first. Yes, you would have to buy and use one more kit before using the regular one. In conclusion, you will need to do: 1) Bleach Kit, 2) Light Brown Color Kit (regular). However, some more expensive kit, do include a Bleach, so do read the package before you buy.
For Dark Brown Color:
To save money, and be better to your hair, you can just use a Regular Color Kit. Yes, your existing Black hair will only change slightly, but if Dark Brown is what you want, you can not really tell the difference. So you do not not need to waste money, and will have a less chance of damaging your hair.
I hope this help you. Good Luck,
