Answer 1

For your updated question this should be good guide:
<table>
<?php
//database connect
include 'con.php';
//get day from event
$sql = "SELECT day, color FROM events";
$result = mysqli_query($con, $sql);
$sqldates = array();
$colors = array();
while($row=mysqli_fetch_array($result)){
array_push($sqldates, $row['day']);
array_push($colors, $row['color']);
}
//first day
$firstday = '1';
$two = cal_days_in_month(CAL_GREGORIAN, 8, 2018); // 31
//for loop get all day in month
$counter = 0;
for ($number = $firstday; $number <= $two; $number++)
if (in_array($number , $sqldates)) {
echo "<td width=50 bgcolor='$colors[$counter]'>$sqldates[$counter]</td>";
$counter++;
} else {
echo"<td width=50 bgcolor='#1e8e8e'>$number</td>";
}
?>
</table>
Note that you need to have defined color for each day, otherwise you will get "Undefined offset" notice.

Answer 2

You are trying to echo an array. Instead you should echo a value from that array with specified index. If I am not wrong, this should work:
//first day
$firstday = '1';
$two = cal_days_in_month(CAL_GREGORIAN, 8, 2018); // 31
//for loop get all day in month
$counter = 0;
for ($number = $firstday; $number <= $two; $number++)
if (in_array($number , $sqldates)) {
echo"<td width=50 bgcolor='#f44242'>$sqldates[$counter]</td>";
$counter++;
} else {
echo"<td width=50 bgcolor='#1e8e8e'>$number</td>";
}
