Oooohhh, exciting! Deep pinks encourage selfless love and show you are a loving and compassionate person. Too much soft pink gives off a needy vibe - emotionally dependance. So stick with the brighter colours for dates. Avoid stark neutrals and especially you want to stay away from an all-grey outfit as it can give off a lack of personality or opinions.
If you are feeling nervous and in need of a confidence boost, wear a little red. Don't go overboard, however, as red can be perceived as stand-offish. This is also going to depend on the type of job you are going for - if you are needing to impress and show your strength then lead with warm colours. If you need to show your potential boss that you are approachable and will be a good listener, you'll be better served with cooler colours.
To draw people to you, wear some yellow or orange. Orange tells people you are comfortable in your own skin, while yellow sends the message that you are lively, interesting and a good communicator. Balance with neutrals, but don't go overboard with black "power dressing". Black tends to send the message "I'm important, notice me, but don't approach me" - pretty much the opposite of what you need in a networking situation.
Blue is the colour of communication, and will increase the flow of ideas clearly between you and whomever you are speaking with. If you are needing to communicate complex ideas and make sure you get buy-in from your audience, blue is the colour for you. If the concepts you are presenting are creative in nature, move more towards a turquoise hue to promote your communication skills and that you have fresh and exciting new ideas. If you are expecting to have to strong arm someone into a decision, add black to your outfit for strength. On the other hand, if you want to avoid confrontation, add magenta: but not pink, you don't want to end up a push-over!
Whether you're sitting them or studying for them, colour can help you in your exams. Wear yellow for clarity and concentration and blue for your memory. Try to avoid purple/violet as those are the colours of imagination and might cause your mind to wander. Unless it's a creative writing exam, and then maybe go for it!
