Display devices such as computer screens have their own display properties. If the display is unbalanced, the image are not displayed with proper brightness and colors. Adjust the properties of the device.
Light shining into the display has an effect on how the image is seen on the display. Avoid direct sunlight and confirm the image where an appropriate illuminance is assured.
Colors may differ from what you see on smart devices such as smart phones or tablets with high-resolution displays.
Colors on a display are not quite identical to those on paper because the display device and the printer have a different process of producing colors.
