Pascal - Set background to white (not grey, pure white)

Question

Is it possible to set console background in Pascal to pure white? I'm no satisfied with

TextBackground(White);

I can use WinApi functions if that changes anything. I know that background in console can be set to pure white (not grey). I once saw program with it. I think it was batch script. But I would like to achieve it in console. Any trick will do. It can be very low level if there is no other way.

UPDATE. I found batch command.

"COLOR arg"

I know I can use it in C++ by using

System("COLOR fc");

But I can't find any "System" command in Pascal.

You can use this code

swapvectors;  exec('cmd','/c color f0');  swapvectors;

This is a command prompt to set console window color

f : Light white : Background
0 : Black : Text color
You can go to cmd, type COLOR /? to know more

To use this code, you must uss DOS unit.

Sorry about my English, I am student.

Hooch, you're right.

if I call TextBackground(White); or TextBackground(White); this get grey color.

For pure white need write TextAttr:=$f0;, where $f_ is background color (white for example), and where $_0 is text color (black for example).

You can change the background to white and then textcolor to blink and clear the screen.

TextBackground(white); TextColor(Blink); Crt.ClrScr;

Right Click top of CMD window -> Properties -> Colors -> Choose whatever you want.

Also try TextBackground(15);

I want to do if from inside my program. – Hooch Dec 30 '12 at 00:13
did you try 15 as parameter? – SergeyS Dec 30 '12 at 00:18
Yes. White = 15. I also tried typing "15". It is still grey. Not pure white. – Hooch Dec 30 '12 at 00:20
HighVideo changes nothing. Or very little. But BG is still grey. – Hooch Dec 30 '12 at 00:25
BTW, which compiler you are using? – SergeyS Dec 30 '12 at 00:26
Lazarus is the choosen one. – Hooch Dec 30 '12 at 00:27
This is because of compiler.. Try to specify 7 explicitly, in general try all numbers from 0 to 15 :) – SergeyS Dec 30 '12 at 00:31
This is what I'm talkig about. http://i.imgur.com/WtKfX.png I tried all numbers. As you can see on pictrue, white BG is not white. – Hooch Dec 30 '12 at 00:36
