Different color type status can choose as follows.
xml open with a text editor.
admin / view / template / dashboard / recent.tpl

after

<tr class="<?php if($order['status']){ echo 'successfull'; } else { echo 'unsuccessfull'; }?>

add type status

<?php if($order['status'] == "pending"){ echo 'pending'; }?>
<?php if($order['status'] == "cancel"){ echo 'cancel'; }?>

--------------------- example-----------

<?php if($order['status'] == "xxxx1"){ echo 'xxxx1'; }?>
<?php if($order['status'] == "xxxx2"){ echo 'xxxx2'; }?>
<?php if($order['status'] == "xxxx3"){ echo 'xxxx3; }?>
<?php if($order['status'] == "xxxx4"){ echo 'xxxx4'; }?>

------- end example --------

so as type staus have orders. Once you have finished adding ended with

">
]]></add>

Repeat the same for admin / view / template / sale / order_list.tpl

<tr class="<?php if($order['order_status']){ echo 'successfull'; } else { echo 'unsuccessfull'; } ?>
<?php if($order['order_status'] == "pending"){ echo 'pending'; }?>
<?php if($order['order_status'] == "cancel"){ echo 'cancel'; }?>">
]]></add>
--------------------- example-----------

<?php if($order['order_status'] == "xxxx1"){ echo 'xxxx1'; }?>
<?php if($order['order_status'] == "xxxx2"){ echo 'xxxx2'; }?>
<?php if($order['order_status'] == "xxxx3"){ echo 'xxxx3; }?>
<?php if($order['order_status'] == "xxxx4"){ echo 'xxxx4'; }?>

------- end example --------

Finally, we conclude with the style of display

admin / view / template / common / header.tpl

----------------- --------- Original file
<add><![CDATA[<style>.successfull td{color:green;font-weight:bold} .unsuccessfull td{color:red}</style>]]></add>
-------------------------------------------------- -------------
We modify it to add color to the status of orders


<add><![CDATA[<style>.successfull td{color:green;font-weight:bold} .unsuccessfull td{color:red} .pending td{color:orange} .cancel td{color:blue} .xxxx1 td{color:You color} .xxxx2 td{color:You color} .xxxx3 td{color:You color} .xxxx4 td{color:You color}</style>]]></add>
