latex problem

Hello all,

It may not be the right place to post this question, but I would like to
give it a try.
So I wanted to install a new package to the latex that I have, it is
latex2e. The package that I tried to install happened to be the color
package. So after creating sty file, I put it in the input directory
which is base. Now, when I include the package in the tex file. It could
not find it. Is there anything else I need to do before using the
package.
Any help is appreciated.
