about idx subtitle

[sg999]

anybody know how to change idx sub colour?
this is my idx sub

# VobSub index file, v7 (do not modify this line!)
#
# To repair desyncronization, you can insert gaps this way:
# (it usually happens after vob id changes)
#
# delay: [sign]hh:mms:ms
#
# Where:
# [sign]: +, - (optional)
# hh: hours (0 <= hh)
# mm/ss: minutes/seconds (0 <= mm/ss <= 59)
# ms: milliseconds (0 <= ms <= 999)
#
# Note: You can't position a sub before the previous with a negative value.
#
# You can also modify timestamps or delete a few subs you don't like.
# Just make sure they stay in increasing order.


# Settings

# Original frame size
size: 720x480

# Origin, relative to the upper-left corner, can be overloaded by aligment
org: 0, 0

# Image scaling (hor,ver), origin is at the upper-left corner or at the alignment coord (x, y)
scale: 100%, 100%

# Alpha blending
alpha: 100%

# Smoothing for very blocky images (use OLD for no filtering)
smooth: OFF

# In millisecs
fadein/out: 50, 50

# Force subtitle placement relative to (org.x, org.y)
align: OFF at LEFT TOP

# For correcting non-progressive desync. (in millisecs or hh:mms:ms)
# Note: Not effective in DirectVobSub, use "delay: ... " instead.
time offset: 0

# ON: displays only forced subtitles, OFF: shows everything
forced subs: OFF

# The original palette of the DVD
palette: 0000e1, e83f07, 000000, fdfdfd, 11eb10, ea12eb, faff1a, 095d76, 7c7c7c, e0e0e0, 701f03, 077307, f3a8b2, f6ea34, f2b62c, f08986

Have you tried change the color using the tool in vobsub? See https://forum.videohelp.com/topic358966.html

Yeah, use VobSub Configure to change the colors. Check the "Custom Colors" box and then change and save the colors. Much easier.
