CUE's platform extends standard six-character hex codes to eight characters by appending two additional characters that control opacity and represent the alpha channel. When you enter a standard 6-digit hex code (for example, #0000FF for blue), the system automatically appends 'FF' to the end, displaying it as #0000FFFF. The 'FF' represents 100% opacity, meaning the color is fully visible.
You don't need to manually enter these extra characters‚ simply enter your standard 6-digit hex code and the system will handle the rest. To adjust opacity, use the opacity slider. As you move the slider downward, those final two characters change to reflect the new transparency level. For a completely transparent element, drag the slider all the way down to zero, which makes the element fully invisible. This is useful for achieving clean designs‚ for example, if you want your poll prompt to appear directly over a custom background image without any additional color overlay, you would set the poll prompt background opacity to zero.
One important note: if you have both a background color and a background image configured, the image will always take precedence and override the color settings.
