1）颜色含义
1：海蓝；2：浅清；3：黄色；4：浅蓝；5：青色；6：红色；7：橙色。
（1）首位为主颜色；
（2）次位为辅助颜色；
（3）末位为0时，表示首位数字表为表格的底色；
末位为1时，则表示以1为底色，首位数字则表为表格字体的颜色；
末位为其它颜色时，则表示底色为ALV的默认颜色；
以上三条是本人大概总结出来的规律，本人发现的现象基本如上，但也不一定全部正确。
其中C200与系统标准ALV底色比较相似；C410与系统标准关键字颜色比较相似。
2）列颜色：
在 slis_t_fieldcat_alv-emphasize 中，写入需要的颜色代码。
Eg:
DATA: fc TYPE slis_t_fieldcat_alv WITH HEADER LINE.
fc-tabname = 'ITAB'.
fc-fieldname = 'COL'. "列名
fc-emphasize = 'C100'."颜色
append fc.
设置ALV字段fieldcat属性：i_fieldcat-emphasize = &3. "颜色
把fieldcat属性写入属性内表allfields：alv_append_field 'WERKS' '工厂' 'C110'.
C110：为颜色代码；
data: i_fieldcat TYPE slis_t_fieldcat_alv WITH HEADER LINE
i_fieldcat-emphasize = 'C100'. "颜色代码
3）行颜色：
（1）在内表itab定义一个字段style来存储颜色；loop内表itab，在需要显示颜色的行为其值赋为颜色'C110'；
（2）在定义alv显示格式定义：
设置ALV显示layout属性：i_layout-info_fieldname = 'STYLE'，STYLE为内表定义的存储颜色的列名。
a.在要输出的 itab 中，加入 color 列，类型为C（4），记录需要的颜色代码。
b.设置 layout。alv_layout-info_fieldname = 'COLOR'.
Eg: DATA: BEGIN OF itab OCCURS 0.
INCLUDE STRUCTURE itab.
DATA: color(4) TYPE c.
DATA: END OF itab.
DATA: alv_layout TYPE slis_layout_alv.
"内表赋值
itab-matnr = '123'.
itab-color = 'C200'.
APPEND itab.
alv_layout-info_fieldname = 'COLOR'.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
is_layout = alv_layout
TABLES
it_outtab = itab.
4）单元格颜色
单元格颜色属性：LVC_S_SCOL(类方式) ，该属性为一结构，含三个字段：FNAME(30)、COLOR（颜色结构，含三个字段：col(10)、int(3)、inv(10)）、NOKEYCOL(1)（覆盖码颜色）
单元格颜色属性：slis_t_specialcol_alv，该属性为一结构，含三个字段：FIELDNAME(30)、COLOR（颜色结构，含三个字段：col(10)、int(3)、inv(10)）、NOKEYCOL(1)（覆盖码颜色）
eg：
定义内表itab含字段FLDNAME type LVC_S_SCOL；
定义内表itab含字段FLDNAME type slis_t_specialcol_alv；
ALV列属性：coltab_fieldname = 'FLDNAME'.
DATA: BEGIN OF itab_test3 OCCURS 0.
INCLUDE STRUCTURE itab_test.
DATA: FLDNAME TYPE slis_t_specialcol_alv.
DATA: END OF itab_test3.
定义单元格颜色结构内表cellcolor type slis_t_specialcol_alv with header line；
循环内表，当要设置单元格颜色所在的列字段colname要设置颜色时
refresh cellcolor.
cellcolor-FIELDNAME =‘COLNAME’. "列名
cellcolor-COLOR-col =‘2’.（颜色代码）
cellcolor-COLOR-int =‘1’.
cellcolor-COLOR-inv =‘0’.
APPEND cellcolor.
CONCATENATE '2' '10' INTO itab_test3-colname. "把颜色值赋给该列
" 更新内表对应存放字段
itab_test3-fldname[] = cellcolor[].
APPEND itab_test3.
" 显示单元格颜色
