Please ladies, enjoy your kitchens - you have to live with them all day every day. Unless you are thinking of selling in the really short term then have what you love - the next person will probably replace it all anyway, especially if you plan on being in your home for even 10 years. Kitchens are changing so much with all the new technology and products coming on the market. Mcctrish more photos of your kitchen would be helpful, I really can't comment too much with the photo you have provided, but I have just totally redone my kitchen (all for me) and I intended having a glass splashback but when the time came, I found it was just too plain and would do nothing for my kitchen. I think with the glass, you need to have a stunning feature colour to make it effective. That was my problem, there was no colour I could have to make it 'sing'. Look at photos on Houzz and you will see that glass splashbacks are the feature of kitchens. Start with the splashback before you decide anything else. Also, if you are just replacing your doors, are there any other fixed panels in the room that will be replaced also or will it be necessary for them to stay, which will then affect what you choose.

Dulux "natural white" is a warm white and works really well. You really need to consider the existing style of the house,what style the space is and what colour you are having on the adjoining walls. If you want a really crisp white then you can do a "vivid white" See the Dulux Whites colour card and you can easily see the variations

Painting over cabinet doors can be tricky, depending on what material you're painting over. An easier alternative is just to replace the doors and drawers, and you can do this very cost-effectively by going for a plain melamine colour like this: If you have open cabinets instead of open shelves, it helps to keep the dust off but they still look great. Or you could go for wall cabinets either side like this:

I would stick with the natural white for cabinets... if your wanting white again.
