If you have amels that aren't het for anything else (don't carry other genes that they may pass on to their offspring) then there's no way to get anything but normals and amels from them.
Depending on your amels you MIGHT have a chance to get sunglow for example if your amels have very little white on them and you breed them with a sunglow.
If you breed an amel (no hets) with any morph that doesn't include amelanistic gene, you'll only get normals that are het. for both parents' morphs. For example if you breed amel with a lavender you'll get a clutch of normal het. amel, lavender.
If you breed an amel with something that is het. for amel, you'll get normals and amels that are het. for both parents' morphs.
And if you breed an amel with something that has amelanistic genes in it - for example butter (amel+caramel) you'll get a whole clutch of amels het. caramel.
