[C++ Builder 6.0] runtime color change of 1 selected field in DBGrid

Quadran

Hello, I am new here so hopefully I do not something wrong,

I have to make a cell's color change in a DBGrid during runtime,

I am already that far that I can change a full column color change, but
I want each cell to be changed during runtime.

I know for one column it is : DBGrid->Columns->Items[x]->Color = clRed;

Any one having the clue how to select row/column individual ?

It would be a great help !
Thnx
