Changing color of the checkbox - html

Question

I am working on a project and I need the background of the checkbox to be yellow and the color of the tick to be white.
<div class="radio-btn">
<input type="checkbox" name="disclaimer" id="rad-1" required="" />
<label for="rad-1">Yes, please!</label>
</div>
This is my HTML and The styling for it is written below
#rad-1 {
height: 20px;
width: 20px;
accent-color: yellow;
}
The background becomes yellow but the color of tick becomes black
I have tried "Color: white;" and "background-color:white;" but none of these work and the tick mark stays black.
here's how it looks

I leave you a possible example: How TO - Custom Checkbox
First we hide the browser's default radio button
.container input {
position: absolute;
opacity: 0;
cursor: pointer;
}
and now we create a custom radio button
.checkmark {
position: absolute;
top: 0;
left: 0;
height: 25px;
width: 25px;
background-color: #eee;
border-radius: 50%;
}
FULL EXAMPLE
body {
background-color: grey;
}
/* The container */
.container {
display: block;
position: relative;
padding-left: 35px;
margin-bottom: 12px;
cursor: pointer;
font-size: 22px;
color: white;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
/* Hide the browser's default radio button */
.container input {
position: absolute;
opacity: 0;
cursor: pointer;
}
/* Create a custom radio button */
.checkmark {
position: absolute;
top: 0;
left: 0;
height: 25px;
width: 25px;
background-color: #eee;
border-radius: 50%;
}
/* On mouse-over, add a grey background color */
.container:hover input~.checkmark {
background-color: #ccc;
}
/* When the radio button is checked, add a blue background */
.container input:checked~.checkmark {
background-color: yellow;
}
/* Create the indicator (the dot/circle - hidden when not checked) */
.checkmark:after {
content: "";
position: absolute;
display: none;
}
/* Show the indicator (dot/circle) when checked */
.container input:checked~.checkmark:after {
display: block;
}
/* Style the indicator (dot/circle) */
.container .checkmark:after {
top: 9px;
left: 9px;
width: 8px;
height: 8px;
border-radius: 50%;
background: white;
}

Answer 3

There is no efficient way of doing so (As far as I now), but there are some tolls like https://doodlenerd.com/html-control/css-checkbox-generator to generate custom checkboxes where you can edit a lot of stuff.
They work with custom indicators, which get activated, when you click on them using a label.
