i have a funny feeling about my gas cooker smell?

i have a funny feeling about my gas cooker? in the last 3-4 days it has smelt different, more kinda gasy and the flames are really quite blue. Im now not sure if they were always that blue or not? i am using alot of white gloss paint in the hall, stairs and landing at the moment. could the paint fumes be having a reaction when i light my gas cooker hob and making the gas smell funny and burn more blue? or do you think i have a gas problem with my cooker. i have only really noticed this problem since i have been glossing??
