Aircraft X arrival to ZZZ1 and Aircraft Y ZZZ departure were in direct conflict.  An IFR release was received from ZZZ2 approach for Aircraft Y and after Aircraft Y was airborne Aircraft X's data tag was in view on the edge on my radar screen.  I advised ZZZ tower on the situation immediately then passed traffic to Aircraft Y. As the collision advisory appeared a traffic alert was issued where the pilot immediately got the traffic in sight and asked what direction to go.  Aircraft was on an IFR departure climb below the MVA (Minimum Vectoring Altitude) so I advised the pilot left or right turn at pilot's discretion. Aircraft Y turned to avoid.I don't know the current visual aids used by approach for release availability to each facility but I'd advise that their visual aids should be made more effective. A radar software update to where ZZZ1's instrument final turns red if someone has been cleared for the approach would give ZZZ [Tower] better situational awareness and be a home run in terms of ensuring this doesn't happen again.  ZZZ controllers standard radar setting does not allow for view of ZZZ1 instrument arrivals much farther out then 10 mile final but we can always see the final and a change in its color would be noticed.
Tower Local Controller reported a departing aircraft was in conflict with arriving traffic under TRACON control. The reporter advised the departing aircraft who then took evasive action while below the Minimum Vectoring Altitude.
