Hi, i have to do a random change of background colors, previous selected by this four switches. I am using two screens. On the first i have the switches and after you click the button, you go to the second screen where the colors have to be changed. How can i do? ![Cattura](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/3/836ec9d2a0d050bfad22164b3fc2651c8f20e57b.png) ---

Hi @ALEX_ANTONPIO_NOTORE, welcome to the Thunkable community! đź‘‹ Do you have to use switches? Have you considered using sliders instead?? ---

Is there a way to select single colors? ---

This can be done. Instead of a random number generation block, use a numeric block with the desired color value. Color can be set as follows ![%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D0%B8%D0%B5](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/3/8/38a0f8b3ec7be1362beee4a7e74cdadfccd2527f.png) or #ff0 #f0f8 hsl(200, 100%, 50%) hsla(200, 100%, 50%, 0.1) rgba(0,0,0,0) or “transparent”. ---
