Henna correction? Help!!

Unfortunately, you cannot get all three of those colors at once with plant dyes and an "intense cherry red" may not be possible - but the color I'M thinking of probably isn't what you mean, however when I read that, I think more of a color you'd get from a box of crayons or out of a computer printer, something henna cannot produce.

If you do black, that's what you're going to get and any henna over it wont change anything. You can shoot for a more reddish brown or cherry cola sortve color. You could possibly get a sortve mahogany color, but it wont be as RED as what you'd get from a box dye, I'm pretty sure. You can also get more of a burgundy color with repeated applications of just henna.

Note: I understand you might already be aware of all that, but it was said in case you didn't and any one new who happens to come across your post.

To correct the orange... you can do a brief indigo gloss, but I'm not sure how well it will hold and it will give you more of a brown color. You can also apply straight henna for a longer period of time to reduce the orange and give it more of a rich red-brown. You could do a hennigo mix to give you more of a brown, and then apply henna over that to bring out more red.

The African one would get you there, it would just take a few more applications than Twilight.

Best method to do it without too much hassle... mix the henna, let it dye release. Freeze it in ziplocks mushed flat. Once its totally frozen, thaw gently (in fridge or on counter) and apply on freshly washed hair for 5 - 6 hours. Wash out, repeat probably two or three more times. Maaaaybe 4.
