can anyone solve this

During a two-day Navratri event, eight different lights — L, M, N, O, P, Q, R, and S — are installed around a circular stadium. Some of these lights face towards the stadium, while others face away from the stadium to illuminate the outer area.
Each light displays two different colours — one on each day — selected from Pink, Red, Blue, Orange, White, Green, Violet, and Yellow. No two lights display the same colour on the same day. The positions of the lights remain unchanged on both days.
The following clues are provided:
* P, which displays Red on Day 1, is placed second to the left of R, who displays Blue on Day 1.
* Also, P and R face in opposite directions.
* P is placed next to the lights that display Blue and Orange colours on Day 1.
* Q is immediately to the left of the light displaying Blue on Day 1. Also, Q is third to the right of O, who displays Yellow on Day 2.
* The light displaying Pink on Day 1 is positioned second to the right of O, and O does not face the centre.
* N and S are placed immediately to the right of each other. Neither N nor S is adjacent to R.
* The light displaying Pink on Day 2 is positioned adjacent to S. Also, N displays Green on Day 2.
* L displays White on one of the days, and M displays Red on one of the days. Additionally, M never displays Pink or Blue on either day.
* N never displays Violet on any day.
* The light displaying Green on Day 1 is positioned immediately to the right of the light displaying Yellow on Day 1.
* S never displays Orange on any day.

This is the valid solution if R displays blue on DAY 2
