i have tried Schev blue light, Phtalo blue, ultramarine and manganese with no results

so you tried these and they were not chromatic enough, or the wrong hue?
Be sure to place your mix in the same context, next to the same flesh tone.

I’d just jump for Prussian + White. The color you are viewing is less chromatic than it seems for one, and secondly the blue is very cyan leaning and I find that prussian is slightly more cyan leaning than Phthalo.

This!
BTW, Phthalo is the most chromatic blue color among other pigments except UMB and much more chromatic than Prussian blue. If you want to make a Blue (or Red) color to look brighter, then avoid to use pure White color on your painting, use pure White from tube to mix blue color with Phthalo, but avoid to apply this White on canvas. White must be muted strongly with Mars Violet, Green Earth, Yellow ochre or VanDyck Brown. Or with a mixture of such colors and Mars Black. Add as much earth color to white as possible until paint looks “White” for human perception.
