right, "equals" is a String comparison and == is Object comparison.
More precisely, ".equals" is the IDENTITY testing operator/method defined on
"String" objects (assuming "colors" is a String), and == is the default
IDENTITY testing defined on java.lang.Objects.
Try this:
String colors = new String("colorchart");
if (colors == "colorchart") System.out.println("colors == \"colorchart\"");
else System.out.println("colors != \"colorchart\"");

The first example tests for IDENTITY and will only be true if variable
colors contains the same object created by the literal "colorchart". The
second tests for EQUALITY and will return true if colors contains the value
"colorchart".
