Instructions for creating a vibrant pathway using colorful tiles

Is there a way for me to create a path of colored tiles for a character to follow, where the character's path matches the color of the character cube itself? I currently have this code (found in another post):

    <html><head>
    <style>
        body{ background-color: lavenderblush; padding:10px; }
        #canvas{border:1px solid blue;}
    </style>
    </head>
<body>
    <canvas id="canvas" width="1000" height="1000"></canvas>
                           <script type="text/javascript">

        var canvas=document.getElementById("canvas");
        var ctx=canvas.getContext("2d");

        var cw=canvas.width;
        var ch=canvas.height;

        var colwidth=cw/20;
        var rowheight=ch/20;

        for(var y=0;y<20;y++){

        for(var x=0;x<20;x++){
      
        ctx.fillStyle=randomColor();
        ctx.fillRect(x*colwidth,y*rowheight,colwidth,rowheight);
        ctx.strokeRect(x*colwidth,y*rowheight,colwidth,rowheight);
         }}

        function randomColor(){ 
        return('#'+Math.floor(Math.random()*98765432).toString(16));
        }
    </script>

</body></html>

<html>
<head>
<style>
body{background-color:ivory;padding:10px;}
#canvas{border:1px solid red;}
</style>
</head>
<body>
<canvas id="canvas" width="1000" height="1000"></canvas>
<script type="text/javascript">

var canvas=document.getElementById("canvas");
var ctx=canvas.getContext("2d");

var cw=canvas.width;
var ch=canvas.height;

var n = 20;

var colwidth=cw/n;
var rowheight=ch/n;

var colors = [];
for(var y=0;y<n;y++)
{
  colors[y] = [];
  for(var x=0;x<n;x++)
  {
    colors[y][x] = randomColor();
  }
}

var road_color = randomColor();
var x = n/2;
var y = 0;
while(y < n)
{
  colors[y][x] = road_color;
  var path = Math.floor(Math.random()*3);
  switch(path)
  {
    case 0: //try left
      if(x > 0 && colors[y][x-1] != road_color) x--; break;
    case 1: //try right
      if(x < n-1 && colors[y][x+1] != road_color) x++; break;
    case 2: //down
      y++; break;
  }
}

for(var y=0;y<n;y++)
{
  for(var x=0;x<n;x++)
  {
    ctx.fillStyle=colors[y][x];
    ctx.fillRect  (x*colwidth,y*rowheight,colwidth,rowheight);
  }
}
for(var y=0;y<n;y++)
{
  for(var x=0;x<n;x++)
  {
    ctx.strokeRect(x*colwidth,y*rowheight,colwidth,rowheight);
  }
}

function randomColor(){return('#'+Math.floor(Math.random()*0xFFFFFF).toString(16));}
</script>
</body>
</html>

It seems like the intention was to create a random path on a grid of colors. The code generates a grid of random colors and then creates a path with a specific color going down the grid. Also made improvements to include a full range of random colors and consistent line weight.
