Conflicting signs

I’m very new to asking spirit guides for help and signs, but I have been consistent in my ask and signs I choose. Today I asked my spirit guides if something specific will happen and asked to please show me a rainbow by bedtime if it would happen, and a lime green car if it would not happen. About 20 minutes after asking, I saw a perfect rainbow. Then, about 2 hours later I saw a lime green car. I’m so confused.
