The second post on customizing the look and feel of OBIEE - changing the colour of the login screen.
Out of the box OBIEE comes with the light blue login screen:
This can be changed by editing the image file and altering the colour as required.
The image file is called background_blue_whitegradient_.png and is located in the following three directories:
Take a backup copy of the file before beginning.
Now edit the file in your favourite image editor – I’ve used paint shop pro.
The image is just a narrow strip of blue to white fading down the screen.
First set the current colour to the what you need – I usually use the dropper tool to obtain the colour from an existing image (such as a screen-shot from a web site).
Now you need to select the paint brush style, with the default stroke type, but set the size to 500 or higher – this would produce a very large faded circle as the paint brush stroke.
At the very top of the image do one mouse click. Because the image is very narrow you only get a very thin slice of the paint brush stroke, producing the faded colour effect we need.
Save as the image as the original background_blue_whitegradient_.png file and copy to all three directories above overwriting the existing file.
In the browser at the login screen you just need to force a refresh – use Control-F5.
