no...and why would you want to? Be happy with who you are and don't try to blame your dissatisfactions in life with irrelevant things like eye color

First off, the alleles that control hair and eye color are on more than one gene, so it isn't one specific gene, that control the color of hair or eyes. Brown hair is not a mutation. Allele wise you can either have light(blond) or dark hair, dark being dominant. As i stated it is a polygenic trait so varying gene configurations account for shades of hair.

I think that she just wears colored contacts.  Her eyes are naturally brown and she wears blue contacts.

All eye color can change over time because of age or, unfortunately, disease. \n\nEye disease is a cause of color change. So, ask a doctor to examine your eyes if you notice a slow loss of color. The change could be due to Fuch's heterochromic iridocyclitis, Horner's Syndrome, and pigmentary glaucoma, says Brian DeBroff, ophthalmology professor at Yale University. \n\nAging, however, is the usual cause of color change over time. So, yes, Emily. Color can change as we age. It does so for 10 to 15% of the normal Caucasian population. These people's eyes change slowly over many years after they reach adolescence. \n\nHow and why eye color changes - Pigment in the stroma (the connective tissue of the front layer of the iris) gives the iris color. Iris color can lighten if the number of pigment granules in the stroma decreases or if the granules produce lighter pigment. (See figure.) The iris can also lose color if the stroma pigment degrades. \n\nEyes, unlike skin and hair, do not synthesize color pigment continuously. Instead, eyes retain the pigment granules and accumulate them in the iris stroma. So, if the pigment degrades, the eye color lightens.\n\nLikewise, eyes can darken if the number of pigment granules increase or if the granules make darker pigment.\n\nThat's how the color changes. Why does it change? Genetics is the key as experimenters learned by studying twins. They observed the eyes and skin of identical twins and non-identical twins of American Caucasians between the ages of 3 months to 6 years. \n\nBoth sets of twins showed a "darkening with age of both the hair and eye colour," says Sturm. The identical twins changed color together, at essentially the same rate. The non-identical twins changed color but at different rates, which indicates a "strong genetic influence in the timing of these colour changes."\n\nEye color probably changes for the same reason we have one head instead of two: genes. Genes determine all body characteristics — including changing eye color as we age.

My eyes are brown.  But there was this one guy who had these eyes that we hazel, but they were more like a yellowish golden color.  I used to tell him everytime I seen him that he could look like a dog and have those eyes and he could still holla at me.  In the end, he was my boyfriend for about 8 mos.

If both parents have blue eyes, then the child will have blue eyes.  Because blue eyes are a recessive gene, so, blue eyed people only carry blue eyed genes.\nOn the other hand, brown eyed people can be carrying a blue eyed gene, since brown is the dominant gene.  Two brown eyed people, both carrying one blue eyed gene, could give birth to a blue eyed child.\n\nMy aunt has brown eyes, but someone in her lineage had blue eyes.  My uncle has blue eyes.  They gave birth to 3 girls, all with blue eyes.  Which means my aunt was carrying the recessive blue eyed gene and passed it along to her children.\n\nBut, to your question, the only way to definitively say a child will have any particular color eyes is if two people with blue eyes have kids.  Then, the kids will have blue eyes.  In all other cases, the eye color of the children will be unknown.

What color are your eyes normally?  \n\nYou probably have green in your eyes, if they're hazel.  Mine are brown, and ain't nothin gonna turn my brown eyes green!  I also quit smoking, and they're still brown.

No, my best friend has one brown eye and one green eye and she's perfectly normal. It's called "Heterochromia iridium" and is rare in people but common in some dogs.\n\nBTW, the aforementioned friend is not a dog.

Yes, the colour of the eyes can change by using contact lenses. I don't know if it can change by a physical way.

By Mendelian theory, no. (bb= blue, BB & Bb=brown)\nBlue eyes are a recessive trait \nbb x bb = only bb\nNow if they were Brown eyed with the blue recessive trait and a blue eyed spouse\nBb x bb = Bb Bb bb bb\n\n-----------BUT---------------------\n\nMost of us learned the model for determining eye color that G.C. Davenport and C.B. Davenport devised in 1907. The Davenport model wrongly says brown eye color is always dominant over blue eye color, which means that two blue-eyed parents always have blue-eyed kids. We know better now.\n\n"Although not common, two blue-eyed parents can produce children with brown eyes," says Richard A. Sturm, a Principal Research Fellow at the Institute for Molecular Bioscience at the University of Queensland in Brisbane, Australia.\n\nEye color is a complex trait that depends on the state of several interacting genes. The gene that usually decides the issue (blue eyes or brown eyes) is the OCA2 gene on chromosome 15. But it comes in different strengths. A person with a weak form of the OCA2 gene will have blue eyes. Likewise a person with a strong form will have brown eyes. \n\nThe plot thickens, though, because an individual also has other eye-color genes that each has a say in the final eye-color outcome. For example, if one of these lesser genes is strong, it can make the weak form (blue) of OCA2 work much more effectively — almost like the strong form (brown). Then the eye color may be a light brown or muddy grey. In fact, the resulting color can be any shade of brown, hazel/green, or blue depending on the strengths of the interactions.\n\nSo, yes... two blue eyed parents can produce a brown eyed baby.

eye color is determined by two genes, one from the father and one from the mother. Blues eyes require 2 recessive genes, both blue. Hence, if either the mother or father has blue eyes one of the genes is provided. The other parent could have brown eyes, and still have a recessive blue gene. However if that parent has two dominant brown eye genes, the child will be born with brown eyes. The only garauntee is to have 2 parents with both blue eyes.

Grassy I have brown eyes (chocolate color) \nPeople use to sing in the streets when they see my eyes (brown eye girl)

Usually by 6-9 months.  All three of mine were born with blue eyes and they stayed that way.  It doesn't matter if they are preemies.  Their eyes will change or stay the same color just like any other baby.

No, there's loads of different shades/colours of eyes. Mine seem to change from light blue to green to dark blue

it's easy there are some boxes with the hairs u choose they have certin colours that is where u change them from.:)

Blue eyes is a recessive trait.  Someone on both your mother and father's side of the family has blue eyes and you just so happened to luck out genetically.

Well,i as well love my eyes.They are different,they are blue and change shades of blue depending on my mood.\nWow,as for what i dont like,im not sure,not to sound cocky or anything.I just find that everyone should love themselves for how they are.
