what is colour??? Its an illusion, it does not exist.
basically colour is the electromagnet radiations travelling from the object to our eyes(and from the eyes to our brain). The colour of the object depends on the wavelength of the electromagnetic radiations.

The entire creation is made up of 5 basic elements. One of them is vaisantarrr or aggnnii and I feel vaisantarr means electromagnetic radiations.
Now electromagnetic radiatians in the range of 400-700 nm is what makes us see things. From personall experience, within this range, lesser the wavelength, better it is for our eyes and for our brain and for our SPIRITUALITY.
Thats the exact reason why blue is the best colour and red is the worst colour.

im gonna memorise that and recite it to the next person who tells me that wearing a red or green bana would be acceptable or that colour is insignificant.

thanks for this gem of information!

I think white is the best colour, nice and simple.

jathedaar of Akaal takht shud wear white and a very nice dastaar.
jathedaar of Keshgarh shud wear navy blue and shud wear a very big dumalla and shud decorate his entire body with shastars.

According to the Baani that "singhbj" has written for us to reflect on above, I feel as though GuruSahibJi is telling us that colours don't metter. Not that red and green are "bad" to wear...LOL! The beauty in the grass the trees we see are created by GuruSahib...those are GREEN. The BLOOD that flows in your veins is RED. Also created by Vaheguru. Why would u call something created by Him to be "bad"? How ignorant are WE?? Haha!

the shabad is talking about the soul and not the colours we were, so how can we apply this shabad to our appearance gurvahu

as my harinder Singh veerji had studied in his class 10th that VIBGYOR is consisting of seven colors of spectrum that white light breaks into. these seven are natually occouring colors and remaing are formed by combination of two or three of thm. Black is nota color its 'absence of light'.

In my view im agree that all we see only those colors what god make us to see. not only em waves but several others waves, raidations, and energies are created by god. these can be felt only to those who have reach to the Dhur.

while coming to the constituent colors of ViBGYOR "Green" and "yellow" are the color that sooths to ur eyes the maximum . Blue also is having similar effect as it lies close to centre. water is blue, sky is blue.

at the end of the day
what u wear, bana or not
what colrours u wear, read or blue
if u look purataan with shastars or not
if u wear sarblohj or not
if u wear dhumalla or not
none of thi will mater in the face of naam
naam bhagthee with pyaar is the MOST important thing
every thine else is smal compared to this
guru granth sahib je exlains to us how we shud live, and we shud rely on guru granth sahib je
that is our guru, theyll guide us
hoinestly, it reall wont matter if u wear red or green or blue or yellow
it will all come down to guru granth sahib je to guide u as ure guru and naam to set ure athma free

The rvaaj of what is accepted by some as 'Khalsa colours' (blue, orange and white) has it's roots in the Vedic age - and shows that they were already an Indic tradition, Bhai Gurdaas Ji says:

ਰਿਗਿ ਨੀਲਬਰਿ ਜੁਜਰ ਪੀਤ ਸੇਤੰਬਰਿ ਕਰਿ ਸਿਆਮ ਸੁਧਾਰਾ ।
rigi neelabari jujar peet saytanbari kari siaam sudhaaraa|
