Your Color Red Really Could Be My Blue | Color Perception | Live Science
My Red Is Your Blue
About 1 per cent of American men suffer from red-green colour blindness.
Recent experiments challenge the accepted notion that all of us have the same default perception of the colours we see. A person’s red could be the other person’s blue, technically, but still carry with it the same feeling.
Example: The colour of blood (deep red) or the blue sky could seem different to some people while carrying the same feeling or emotion when they encounter it.

My Red Is Your Blue
About 1 per cent of American men suffer from red-green colour blindness.
Recent experiments challenge the accepted notion that all of us have the same default perception of the colours we see. A person’s red could be the other person’s blue, technically, but still carry with it the same feeling.
Example: The colour of blood (deep red) or the blue sky could seem different to some people while carrying the same feeling or emotion when they encounter it.
The Calculations Of Light
- The colour-sensitive receptors that humans have, called melanopsin, measure the amount of blue or yellow light in the atmosphere and likewise regulate our circadian rhythm.
- Human beings have Cone Cells, which are of three types, Red, Blue, and Green, and have evolved much later than the receptors in the brain.
Colour Is A Private Sensation
- Research proves that the universal emotional responses that we have when we see a colour tend to be the same, even if the actual colour is different, as our conscious perception of those colours varies.
- The day-night cycle of living things is impacted by the ambient light, where the morning yellow light awakens us or makes us feel happy, and the dominance of blue light at night makes us feel sleepy.

How refrigerators work
Refrigerators today work by evaporating liquids.
The liquids are pushed through the refrigerator through tubes and begin to vaporize. As the liquids evaporate, they carry heat away with them as the gases travel to a coil outside the refrigerator. Here the heat is released. The gases return to a compressor, where they become liquid again, restarting the cycle.

Bad at delegating

Leaving out the guesswork
Your manager may not put in the effort up front to articulate the expectations she/he has so that you're on the same page from the start. It may leave you guessing what successful completion might look like, and then frustrate you both when you think wrong.
To be fair, at a certain level of seniority, it becomes more reasonable for a manager to expect you to know what you're doing and work out the details by yourself. But even then, a good manager knows when to invest the time to get more aligned on those things.
Dealing with a lack of direction
- Name the issue. Your manager might already be aware of the problem.
- If your boss wants you to take more ownership, you can say that you want to take more ownership for your projects but that you want to do so with confidence knowing what she/he is envisioning.
- You may have to draw those details out of your boss with each new assignment.
- Once you get started on the work, consider giving an early view of your work to your manager, to have a chance to be provided with input early on.
- It may take a few rounds to figure out exactly what something should be.

Negativity-Free Meetings
Preserve your sanity in a VC meeting by these methods:
- Introduce ground rules in the meeting requesting it to be free of negative talk, on the pretext of detoxing the audience/team members and improving their mental health.
- Intentionally keep things positive, promoting sharing of positive things and ending the meeting on a high note, so that the negative is by default kept out, without pinpointing it.
- In case a higher-up or a boss is the one with the negative talk, one can bite the bullet and request the person personally and politely to stop or reduce the negative banter.
Difficulties in connecting with other people
Even tough we are today living in a world where everybody is virtually connected to everybody, there seems to be a serious issue with people actually succeeding to connect with each other.
Make friends and reconnect with old ones:
While connecting and making new friends can prove quite exhausting sometimes, it does eventually pay off. In order to find it easier to know new people, make new friends and reconnect with the old ones:
- Learn to actually ask your friends for the things you want from them.
- Seek professional help to forgive and love yourself first: the empathy that you feel for yourself is a key to the empathy that you end up feeling for the others.
- Learn to say no, even when you fear the possible disappointment that this can lead to.
- Accept your friends without judging them.
- Learn to be honest with your friends: this always goes a long way.
The effects of the unlucky charm
Research shows that lucky charms have real, positive effects. But unlucky things have their own kind of power.
The story behind a physical item we own matters
Assigning luck to an object
There are generally three ways we give luck to an object.
- Through association: A penny you had the day you met your partner.
- Through symbolism: Like a sock with four-leaf clovers or black cats printed on them.
- Magical contagion: The idea that there is some essence or physical property that can rub off from contacting it.
Bad associations
According to research, secondhand engagement rings are much less likely to sell if the listing indicated that the previous owner had been through a divorce or a broken engagement. One explanation is that we believe that various properties can be transmitted through contact.
Sometimes, you create the story yourself. The item has to be prominent in the situation. But if the item is branded as unlucky, it's hard to forget the association.

Phone Interviews: A Level Playing Field
In-person interviews tend to focus less on the skills and experience, and more on who is more cordial or great to talk to. It does help build rapport in some cases, but also promotes an invisible bias towards the candidate’s race, gender, class and other factors unrelated to the job performance.
Phone Interviews level the playing field and let both the parties focus on the essential.
Building Rapport During Phone Interviews
A phone interview can also be used to build rapport, but instead of small talk, one can build up on the conversation, avoiding stiff, rehearsed responses to whatever the employer is asking.
If the conversation is genuine, one can easily connect with the employer on a human level.
