Default Reds with bluish tinge

Red flowers always have a marked bluish tinge. I use a Panasonic FZ20. Other images such as landscapes, birds etc do not show this effect. I have searched the instruction book to no avail. I assume there are camera settings which will solve this problem. Any suggestions would be welcome. Thanks in advance.

This is a typical example of the problem. The flower - a Pyramidal orchid was much redder. Hope the file is attached. Not sure if I have followed the correct procedure.

No photograph to be seen! However, I seem to remember reading somewhere that certain flowers reflect wavelenths that we can not see but film/sensors can and this shows up in the image when on screen or printed.

Sorry Roy, still no pic. When you compose your post, select "go advanced" and if you scroll down below the text entry box, you should see a range of options below, one of which is marked "manage attachments", click on this and click on the "browse" button in the dialogue box presented. Find the file you wish to attach on your computer and then select the "upload" button in the manage attachments dialogue box. Remember that attachments should not really be bigger than 1024 pixels max dimension and no bigger than 200kB file size ideally. You should resize your picture befor you upload it if it is bigger than this.

I played with your photo in Photoshop reducing the blues & reds actually and I could not see any real discernible difference between the two.

Now maybe it's my monitor but this looks more lilac in color than blue. Am I seeing a different color than everyone else?

Yes it looks lilac to me too. If there are a few strong colours in the scene it can often bias the Auto White balance in the wrong direction. I often include part of a grey card in the corner of the frame if I want Colour accuracy.
