How to shoot obvious colour pictures?

the center is white only~i want to get obvious yellow

this is a draft shoot by hp

and a alternative question :
My lens cap had been lost...

Errr... Load it into a photo editor and adjust hue/color?

Correct the white balance...

there is a tutorial in the Digital Darkroom sub forum for correction of jpeg pics.

As for the lens cap, drop by to Peninsular, plenty of shops there to look around. Remember to look for the filter size.
