You want different BLUE hues. To start, out of tube you can get Pthalo Blue(PB), Cereleum Blue(CRB), Cobolt Blue(CB), Utramarine Blue(UB). Identify these colors on color wheel(it is as below):
---SET-1
[violet]
UB
CB
PB
CRB
[green-blue]
2)
Now above Blues have compliment in ORANGE and YELLOW-Orange, and those compliments colors are Burnt Sienna (BS), Burnt Umber(BU), Raw Sienna(RS), Burnt Sienna(BS) and Yellow Ochre(YO).
Identify these colors on color wheel(it is as below):
---SET-2
[orange]
BS
BU
RS-YO
RU
[yellow]
3)
Now mix both SET-1 and SET-2 to get different compliments. These compliments are going to be dark, say these mixes as SET-C.
4)
Now you can mix both SET-1 and SET-C to get various dull blues. I say dull because colors in SET-C is going to kill the chroma of SET-1
However you try, it is impossible to comeup with definite formula or procedure to achieve this. You have to experiment with the colors that you have; basically it is very very confusing. You better write down the results.
