majority of pieces on white squares
with modern desktop publication, is this still a standard practice to aid solvers'eyes?

Yes, but not universally so. The technology has improved, but eyeballs are still the same. :-) Actually, mine are much worse nowadays, so every little bit helps.

heh, improved technology only allowed the diagrams to get smaller... the eye strain remains unfixed.
But, frankly, I'm not sure this algorithm is optimal.
Personally, I only find it difficult distinguishing black units on dark squares.
If I dared to assume mine is the common condition, wouldn't "majority of black units on light squares" be an improvement?
Anybody know:
1) From whom did we inherit this system?
2) Has any research been done on its effectiveness?

There can be many who was among the first to use this rule.
One of them is Osmo Kaila (FIN), who insisted this rule always then publishing problems in his columns. He made even an official proposal to PCCC congress that this should become a mandatory rule. To his big dissapointment the proposal was turned down on grounds that each composer can freely select how his problems are.
Osmo Kaila was perhaps few first persons to have three FIDE titles. He was IM otb play, Fide judge both in otb and in problems. He was very proud of these, often mentioning them. Later he got also the Fidemaster title in composing.
Harri Hurme
IM in solving, Fidemaster otb and composing :-)
Hates the too small diagrams in most publications. Paper is not expensive, use it!

And how would You call this rule - FORCS = FIDE Official Right Coloring System - or maybe ...
Sketch  (= 3+2 )
Say: "Once I posted this little (!?) onemover to a contest (!?), and after the publication I realized that my onemover (#1) had turned to a twomover (#2). What happened?"
*(no kidding - other reasons may be imagined for this or that orientation. I remember a moremover - almost a Rex Solus - but the black King was in a light colored square, and all (or almost) of the white pieces were in dark colored squares - (that gave a particular charm to the diagram ... )
A composer can also prefer to show clearences in the clockwise sense, to suggest some kind of inexorability, or sacrifices from right to left (maybe more hard to realize than sacs made from left to right - or vice-versa, depending on the cultural background... (and the orientation becomes more relevant than a mere accounting

Many Thanks Harri!
And, bravo on your hat trick!!
I knew you had two titles...
FIDE International Master of Chess Problem Solving, 1993
FIDE Master of Chess Composition, 2010
And, I confirmed the third in FIDE's rating lists: "500321 Hurme, Harri f FIN 2258 18 ..."
I do wish FIDE's list would show the year in which a title was awarded.
I assume you're busy working on a title in Correspondence Chess, now. :)
@Zalmen,
Funny -- vertical mirror, for a light-square majority, doesn't always work.
But, ugh, the unprovided check. :(

Set-play in a #1 ... well: 'sketch'
Or still: "My #1 had not that superfluous black Pawn, but the Editor, thinking that my #1 wa a cooked #2 etc
Ok, Kevin: But what about a TT !?

Did somebody say Theme Tourney?
Lovely idea -- my kind of TT! -- but first, 6 questions:
1) what exactly is the theme?
a) Any problem which can not be presented in conventional form (with a majority of units on white squares)?? - or -
b) Any problem with a changed stipulation when re-presented in conventional form??
2) can we permit fairies?
3) can we allow any stipulation?
4) can we get a good (and prompt) judge?
5) deadline?
6) where to send (email address preferred)?

O. Kaila
"Ilta Sanomat" 1976
 (= 2+3 )
h#2 2 Sol
Need some explanation ?! (In the mating position - same for both solutions - there`re 3 light-squared and 2 dark-squared units - and the black King dies on dark - or in the dark... )
