Your colour-vision problem is not in question as long you pass the CAD and Lantern Tests, I've seen some very mild color deficient pilots who are more experienced and better than me, however, for a job I suggest you to upgrade to A320 or Boeing 737 in Brazil first, then build up 1000hrs on the type then consider changing the airline/country.
ICAO English 4 is okay but work toward 5 which brings you some good job opportunities in Persian gulf based airlines.
