"blue-coloured" - Translation from English to Arabic

The witnesses stated that there had been no explosion, just the release of some blue-coloured gas with a very bad odour, which had been moved into the soldiers’ direction by the wind.
وأفاد الشهود بأنه لم يحدث انفجار، بل انبعث غازٌ ذو لون أزرق ورائحة كريهة للغاية انتقل بفعل الرياح في اتجاه الجنود.
