Emerald Theme

The Emerald theme is the easiest way to customize the look of your QuizWitz game. By default the theme is a clean blue/green theme with vivid option colors, but by combining quiz attachments and theme modifiers you can change the way it looks drastically.


You can use our theme tester to see what your settings will look like.

Quiz attachments

By far the easiest way to change the look and feel of the game is by attaching images to your quiz. Open the 'Quiz' settings and scroll down to the 'Attachments' section. Here you can upload images that will be used as background, client logo, connect- and wait screens (for conference- and live quizzes) etc.

Round attachments

You can also upload images or videos that will be played before and after the game. This goes for rounds as well: find an image that you want to use as round introduction, go to round settings, disable 'Show round intro' to hide the default round introduction and upload your image or video as 'Show before round'. When the round starts the image or video will be displayed instead of the default introduction.

Use images and videos of a 1920x1080 resolution for best results.


After playing with the attachments, we end up with something like this.

All music in the game can be replaced with attachments as well. Any audio files uploaded in the 'during question' slots will be played during the question countdown.

Emerald theme modifiers

In addition to attachments, you can also manipulate the Emerald theme with 'query parameters'. These are parameters you can add to the 'advanced game options' URL and that change the look of the theme.

For this we will start with an example quiz (without any attachments)

When you start the above quiz, the game will be in default Emerald style. Let's change that.

The available modifiers are:

  • backgroundColor
  • mainColor
  • accentColor
  • timerBackgroundColor
  • headerTextColor
  • optionTextColor
  • optionColors (4 colors comma-seperated)
  • optionBorderColors (4 colors comma-seperated)

Additionally, you can set a default font:

  • defaultFont
  • headerFont

These fonts must be URLs to publicly available font files.

Each of these modifiers can contain a single color in html hex format (ff0000), or a linear gradient by providing multiple colors divided by a minus symbol (-, for example ff1b6b-45caff). (Note that the # symbol should not be added)


The query parameters must start with a questionmark (?) and each parameter must be devided with an ampersant (&). For more information on query parameters, visit wikipedia.

By adding these parameters to our game url, we modify the colors in the theme:

The easiest way to experiment with these parameters is by using our theme tester. When you are done experimenting you can copy-paste the parameters to your advanced game options url.
