Replacing grout is certainly one way to fix the problem. Instead, use UltraCare Grout Refresh, a water-based color seal, available in 40 standard grout colors. It's made for refreshing the look of old, discolored grout, or completely changing the color of the existing grout. Don't replace it, Grout Refresh it!
No, you cannot change the colour without re-grouting. It would require the grout to be raked out and then grout again with desired colour.
The only thing you can do to immediately even out the color, and/ or change its shade, would be to use a grout colorant. You can change any color to any other color, and in so doing, make the grout easier to keep clean and, at the same time permanently seal it.
If you are really unhappy with the color, I recommend you try the Grout Shield to ``fix'' it. Go to a hardware store and get paint color chips, pick out the color you want, then mail it to Grout Shields (after contacting them, of course). They will mix exactly the color you want; it is not hard to apply and it lasts.

For discoloration, use some form of bleach until it's white again. If colored grout, use an appropriate cleaner.
The Grout Pen
It's the perfect solution for cleaning shower grout because it takes much less time to get a better finish and it dries within 30 minutes.
You can apply new grout right over the top of the old grout. To do this, all you need is a grout removal tool. Use the tool to strike out the old grout, making sure the depth is at least 2mm, which is about the thickness of two dimes stacked one on top of the other.
Grout almost always appears darker when wet than when dry. New grout can take 24 or even 48 hours before it's completely dry. It depends on the humidity and temperature in the room where the grout is installed.
Remove and Replace Grout
The most thorough and complete solution is to remove the grout and install new, grout in the color of your choice. In small areas, such as backsplashes and tub or shower surrounds, this project can be less difficult than you might imagine.
Mix the bicarbonate of soda and water to make a paste. Apply this solution directly to discoloured grout using either a stiff-bristled brush or your fingers.
Grout can be recolored by removing the grout and replacing it with new grout that has been tinted the color you want. Removing and replacing the grout works for all types of tiles.
Grout pens will only temporarily cover your grout's discoloration. That's probably why they are the cheapest option available. We run into the infamous grout pen issue nearly every other week. The project usually goes awry when the homeowner applies the grout pen to the grout and some bleeds over onto the tile.
Changing grout color is an inexpensive DIY project. If you're painting the grout with a colorant, the supplies should cost you less than $40.
It does work well, however some reviewers suggest it is not always successful at removing offending stains from the grout itself.
And not just new —color sealing can completely change your grout to virtually any color you choose. The benefit of this is obvious. Are you considering new decor, an updated, fresher look or more contemporary colors? Your existing grout doesn't need to hold you back or limit your choices.
There are plenty of products on the market that will allow you to do this, and some of them are sealants as well as stains, which will save you a step. Once you've cleaned your grout and chosen the right stain, you simply paint the dry grout with the stain and paintbrush, allow it to dry, and clean off the excess.
Hydrogen peroxide has so many uses, and it's especially good at brightening discoloured grout. Unlike vinegar, which can corrode the grout over time, hydrogen peroxide is a gentle disinfectant that is non-toxic – when used correctly. To clean grout, simply pour undiluted hydrogen peroxide into a spray bottle.
How it works: Touted as a miracle cleaning paste, The Pink Stuff is easy to apply to grout using a soft cloth or sponge. Simply rub and scrub, and then rinse with hot water. As a mildly abrasive cleaner, the paste has a little grit to it, which helps scrub away dirt and debris from grout and surfaces.
Use Vinegar And Water
For mild grout stains, the best option is vinegar. Vinegar will help to restore your grout to its original healthy state. You need to dilute the vinegar with equal parts of lukewarm water. Spray it in the grouts and let it stand for 5-7 minutes.
Some professionals swear by a simple mixture of baking soda and peroxide to clean grout. Hydrogen peroxide is an acid, and baking soda is a base compound. Mixing the two together creates a reaction that can penetrate the grout lines and free dirt and debris.
You don't have to remove all of your old grout to apply the new grout. The new grout can be applied right over the top of the existing grout. You will need a grout removal tool, which is a small tool with a sharp blade capable of chipping away the grout.
