  One easy way to check: look in the USNO A2.0 catalog
(which you can find via SIMBAD), and compare the
"Bmag" and "Rmag" numbers.  For your star, at

       RA =  06 54 13.527
      Dec = +07 56 29.06

the USNO A2.0 lists B=12.4, R=11.1.  The difference
is called the "B-R color" of the star -- in this instance,
B-R = 1.3.  A run-of-the-mill star will have a B-R color
anywhere between 0.5 and 1.5.  A red star might have
a B-R color of 2 to 3, and a REALLY RED star can have
B-R colors greater than 3 or 4.  
 
  Even easier way: compare the TASS magnitudes in V and I
for your star.  The "V-I color" shouldn't be too different from
the "B-R color", with values greater than 2 once again
indicating "very red".  

  Your star has B-R=1.3, and V-I=0.8.  Doesn't look like
"very red" to me...
