What should I do with my hair?

Hi! I have light brown hair and I decided to dye a small streak of it purple. I bought dye called color jamz purple plum. I bleached my hair and then put the dye on it (following all of the directions). The end result is not at all what i expected it to be. The streak looks almost black and is barely noticeable, but in the light it looks indigo and has a green sheen. I do not like it at all and want to know what i can to do make the color more noticeable and less indigo. Please help me! Thanks!
