Yes, we can match to other colours.
However, we do not know the exact colours that IKEA use. You would need to provide us with a relevant colour code.
The easiest way to do this is to take a piece to your local Bunnings and ask them to do a colour match at the paint counter. They will tell you the Dulux colour match name & colour.
If you have a very custom existing colour, a physical paint sample (pot) may be required, which you would need to ship to us.
