The color dot on a ping iron relates to the lie angle of the clubhead relative to the shaft. Depending on your height, how long your arms are and howyou set up, the angle you want changes. During a fitting a golf pro figures out what angle is best for you and has a chart for what color matches you for the best fit.
Ping K15 Irons, Available with PING Color Code of white dot, silver dot, green dot, black dot, orange dot, purple dot, yellow dot, red dot, gold dot, blue dot, brown dot, maroon dot, etc. Ping K15 Irons, Available with PING Color Code of white dot, silver dot, green dot, black dot, orange dot, purple dot, yellow dot, red dot, gold dot, blue dot, brown dot, maroon dot, etc. The Ping K15 irons have lightweight titanium faces on stainless steel bodies, with the weight saved in the face repositioned to the sole and perimeter. The hybrids, Ping says, are lower-spinning and help golfers achieve a higher launch. The larger K15 iron set combines a lightweight titanium face with a stainless-steel body to increase both forgiveness and launch conditions. The titanium face insert allows for increased ball speeds across the entire hitting surface and the steel body construction gives players the patented Ping feel that folks from around the globe have come to love and trust. K15 irons is also made with an offset hosel, which helps to lower the spin by allowing you to close the club face easier at impact. Golfers will be amazed when they pull these babies out and give them their first test run. Many of those that have already started to play these irons and hybrids are thrilled with the performance that they are getting out of them. Source From golffastbuy.com
Ping introduced the Ping Colour Code system in 1972, so some of their earlier irons did not have the dot.
When you get a set of Ping irons custom fit, the use your height and where on the sole the club strikes the ground to give you a colour code. This colour is usually a little dot on the club. For example, black is standard, blue is 0.75 degrees upright, and gold is 4 degrees flat.
Please see related link. The lie angle for irons varies from club to club due to length. Black dot is standard so the lies noted in the related link are accurate.
If you're observing a bright orange dot high in the sky at night, it is likely the planet Mars. Mars can appear orange or reddish in color due to its iron-rich soil and atmosphere. It is one of the most easily visible planets in the night sky and is often mistaken for a distant star or aircraft.

Yes, the black spider with an orange dot on its back is likely a black widow spider, which is venomous.
Use a protractor, or computer software such as GeoGebra (available for free).To draw an an angle of specified measure with a protractor:Draw a straight linePlace a dot at one end of the line. The dot represents the vertex of the angle.Place the center of the protractor at the vertex dot and the baseline of the protractor along line you drew (an arm of the angle).Find the required angle on the scale and then mark a small dot at the edge of the protractor.Join the small dot to the vertex with a ruler to form the second arm of the angle.Label the angle with capital letters.
The dot-product of two vectors is the product of their magnitudes multiplied by the cosine of the angle between them. The dot-product is a scalar quantity.
