I need help with matrix color
 

Problem: Write a program that displays a single character in all possible combinations of foreground and background colors (16x16 = 256). The colors are numbered from 0 to 15, so you can use a nested loop to generate all possible combinations.

Here is what I tried, but it doesnot come out right. Could anyone help me, please?. I am a newbie at this language. :(

INCLUDE Irvine32.inc

.data

text BYTE "Hello!"

.code

main PROC

        

        ;mov ecx,17

        mov cx,17

        mov ch,1

        mov cl,4 ; right

L1:

        mov ax,blue

        mov ax,cx

        call setTextColor

        mov ah,ch

        ;dec ah

        call setTextColor

        mov al,cl

        call setTextColor

        ;mov ax,cx + (blue*27)

        call setTextColor

        ;mov eax,ecx

        ;call setTextColor

        mov edx,offset text

        call writeString

        loop L1

        exit

main ENDP

END main
