: I think you're still misinterpreting the OP's original intent. As I
: understand it, he has a form with two (2) text fields where the end user
can
: enter color codes (e.g. #FFFFFF, #000000, etc..). One for background, one
: for foreground. On the server-side, when these color codes are submitted,
: the difference between their brightness levels is calculated. If the
: difference is above a specified threshold, then the color code values are
: stored (perhaps in a database), if not the user is redirected to a page
that
: indicates there is insufficient contrast between the foreground and
: background colors specified. I don't think there's any client-side going
on
: in this scenario. I imagine this is for some skinning/personalization
: functionality on the website.
I'm willing to concede I'm missing it but I don't see how you get that out
of this statement:
"I want to validate if background color is dark then only light colors
should be entered in text. and vice versa."
"I want to validate if background is dark." Following your conclusion, the
value has already been selected.
"THEN only light colors should be entered in text." The user is entering
the text, or selecting from a list, but can only enter/select colors that
are in contrast with the background they have already chosen. To me, this
means the options have changed based on the first input and the webmaster
wants to be in control of those options, not the user.
"and vice versa." This means, to me, if background first, foreground
options are based upon that color. If foreground color is selected, then
background options are based upon that color.
His email to Adrienne, parallels what I just wrote.
you got the problem right. I will tell the scenario also i am building a
website where the users can choose there
own color combinations.so when the user selects a color and if it is
bright
color say he has selected the background color then the next selection
should be
light color so that the combination looks good,
This could be a simple list or numerous rectangles/squares on a page of the
color they selected with all of the available options for the contrasting
color for the text. The user could then select the one they want and THIS
could then be added to a database.
I think I've actually seen this somewhere before and it was done all
client-side. It could be done server-side but I think it would be a waste
to do so. We may have to agree to disagree on this one because I just can't
see his comments as anything else.
One last thing, why would the user be directed to a page informing them
their selections are inadequate for contrast? Who the Hell is looking at
this anyway? Isn't it the user? If it's their skinning/personalization
option, then why is the webmaster trying to decide for them? I think the OP
just wants to help the user choose the colors that work best together by
letting them know what the available color options are that would contrast
the most for a better viewing experience. However, I think the OP, while
offering these choices, should not only allow the user to choose a
predetermined pair but also choose any colors they want. Some may like
orange on red. Who am I to deny them that choice? Sounds like fish on
Fridays to me. (O:=
