Set Palette or stylesheet causing my application did not works properly.

Buket

When I assign a button or label for the application, I can get output on the target device, but when I change color, it does not give any output. Do you have an idea about it?

Do you have an idea about it?

No, you do not provide enough information.
"When I assign a button or label for the application" - what does that mean?
"but when I change color" - color of what? And how do you change color?
What device?
What Qt version?

Buket

The device I am working on is ARM-based (Rockchip RK3288, ARM Cortex-A17 CPU, Mali-T760 MP4 (T764) GPU) motherboard.
Qt version: 5.12.2

When I change the color of the button or the color of the label I added using the palette, I cannot get the standard output I get on the target device.
When I debug without using color, I can get output.

@Buket can you write some of your codes here

Buket

.pro file :

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++11

# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

.ui background image code (I add stylesheet for toolbutton):

background-image: url(:/new/prefix1/deneme.jpg);

.qrc file (resource):

<RCC>
    <qresource prefix="/new/prefix1">
        <file>deneme.jpg</file>
    </qresource>
</RCC>

I managed to add color. I can only change the button color when I add the stylesheet as RGB.

background-color:rgb(138, 226, 52)

I still can't see the target device when I add .png file and deploy. Only the standard button appears.

Edit:
I tried deploying using Label and Pixmap but the result did not change.
