You want to avoid shades that are too similar to your natural coloring; beiges, creams, off-whites, stone grays, taupes, etc. These colors will only wash you out and emphasize your gray tones.
If you waited 72 hours before washing your hair after it was bleached, you could use the purple shampoo the next time you shower. If it hasn't been up to 72 hours, shy away from the purple shampoo until your next wash day, so it doesn't potentially ruin your hair tone.
