So far, I have been able to make a variable that will store the hexcode, but I can't figure out how to use that variable in order to change the background color to that color. This is my code so far:
document.body.style.backgroundColor = 'rgb(${redhex}, ${greenhex}, ${bluehex})';
where redhex, greenhex, and bluehex are all variables that the user can change for the RGB. I think that part of the issue might be that I have another variable in my code named rgb?
You might need to use a template string to interpolate other values inside the string. So in your case, it might be
document.body.style.backgroundColor = `rgb(${redhex}, ${greenhex}, ${bluehex})`;
I believe that you could also use this website https://www.rgbtohex.net/
It is a tool I use some times to convert RGB into simple hex values this will replace
rgb(${redhex}, ${greenhex}, ${bluehex}) with ${rgbHexCode}
Resulting in
document.body.style.backgroundColor = ${rgbHexCode};
If I understand you, the variable is hexcode, but then, rgb doesn't take hex values. Rgb takes base 10 values from 0 to 255. Be sure to check if you are sending the right type of value
