Breeding colourful guppies

Hi! My first batch of fry is now nearly 8 weeks old, and I'm starting to think about what sort of make I should be looking for to create colourful fish. I have five females of this age, and they have been separated from their brother. Here are a few (horrible) photos so you can get an idea of their colouring.



Here is a photo of the mother and brother.


The mum has a light green tail with a few black spots at the top and bottom. Most of the fry at developing colours similar to this. What sort of male should I be looking for to reliably produce good looking fish? Should I pick one up of a similar colour and pattern or go for something else?

I also have a yellow female with a pale pink tail who I would love to get fry from, so I male who I could use with her too would be good.

 

I'd mix a blue male in there and see what happens!

 

Any male will give you nice colors

 

I got some interesting colour by mixing green cobra and red something or other. The off spring male was green cobra body with a dark red tail.

 

Okay thank you! My lfs has some purple, some red, and some green/blue (who look similar to my female) at the moment. Mostly I just wanted to check that I wasn't going to an up with brown fish or anything! If I bought two different ones I could put each with a few females and see what happens? I would just have to think of a way to rearrange or divide my tanks.
