What is the colour which is suited to the a9eafe colour?

I am developping a mobile phone application , and I display a dialog box when there are information to show to the user. The background colour of t开发者_C百科he dialog box is a9eafe in hexadecimal form.

I want to add a title bar to the dialog box and I do not know which colour should I set to that title bar so that the a9eafe background colour is well suited to that colour.

So what colour is good for the title bar to be combined with the background colour a9eafe so that the dialog box is user-friendly ?

PS : I want the colour to be expressed also in hexadecimal form because the editor I am using only recognizes hexadecimal colour.

I think there are a lot of options. The best thing you could do would be to try an online palette generator. You could try http://colorschemedesigner.com/
