I need to change the color of console background and the color of the text also in assembly language

Question

The code here is for Hello World simple program in assembly

.model small
.stack 100h
.data
msg db 0AH,0DH,"Hello World","$"
.code
mov ax,@data
mov ds,ax
mov ah,09h
mov dx,offset msg

I just figured out that it is solved by

 mov bl,9; this is for color
 mov cx, 11; this is for number of characters
 int 10h; puts the color behing

Just up on the mov dx, offset msg Also add

 mov ax,4C00h
    int 21h

The working snippet

.model small
.stack 100h
.data
    msg db "Hello World!","$"
.code

main proc
    mov ax,@data
    mov ds,ax

    mov ah,09h
    mov bl,9; this is for color
    mov cx, 11; this is for number of characters
    int 10h; puts the color behing

    mov dx,offset hello_message
    int 21h

    mov ax,4C00h
    int 21h

main endp
end main

I need to change the color of console background and the color of the text also in assembly language
