i am new to matlab & i am stuck at colouring muliple lines in a single graph. The code is as below

close all
sr='EVF  EXPERIMENTAL DATA.xlsx';
% eps_dot=0.1
        data_1=xlsread(sr,'EVF P-LLDPE','C2:C1158');
        data_2=xlsread(sr,'EVF P-LLDPE','D2:D1158');
%  eps_dot=0.3
        data_3=xlsread(sr,'EVF P-LLDPE','E2:E900');
        data_4=xlsread(sr,'EVF P-LLDPE','F2:F900');
%  eps_dot=1
        data_5=xlsread(sr,'EVF P-LLDPE','G2:G360');
        data_6=xlsread(sr,'EVF P-LLDPE','H2:H360');
% eps_dot=3
        data_7=xlsread(sr,'EVF P-LLDPE','I2:I101');
        data_8=xlsread(sr,'EVF P-LLDPE','J2:J101');
%  eps_dot=10
       data_9 =xlsread(sr,'EVF P-LLDPE','K2:K35');
       data_10=xlsread(sr,'EVF P-LLDPE','L2:L35');
data='VIRGIN LLDPE.xlsx';
       % eps_dot=0.1
        data_11=xlsread(data,'Sheet1','A4:A543');
        data_22=xlsread(data,'Sheet1','B4:B543');
      %  eps_dot=0.3
        data_33=xlsread(data,'Sheet1','C4:C650');
        data_44=xlsread(data,'Sheet1','D4:D650');
      %  eps_dot=1
        data_55=xlsread(data,'Sheet1','E4:E306');
        data_66=xlsread(data,'Sheet1','F4:F306');
      % eps_dot=3
        data_77=xlsread(data,'Sheet1','G4:G107');
        data_88=xlsread(data,'Sheet1','H4:H107');
      %  eps_dot=10
       data_99 =xlsread(data,'Sheet1','I4:I17');
       data_1010=xlsread(data,'Sheet1','J4:J17');

   colorstring1 = 'kbgry';
    loglog(data_1,data_2,data_3,data_4,data_5,data_6,data_7,data_8,data_9,data_10,'color', colorstring(1), 'linewidth', 1.5);
    hold on
      loglog(data_11,data_22,data_33,data_44,data_55,data_66,data_77,data_88,data_99,data_1010, '*', 'color', colorstring(1));
    grid on
    xlabel('Time (sec)');
    ylabel('Extensional Viscosity (Pa-sec)');

[bon sai]

Please try to manage line color in axes instead.

loglog(data_1,data_2,data_3,data_4,data_5,data_6,data_7,data_8,data_9,data_10, 'linewidth', 1.5);
    hold on
      loglog(data_11,data_22,data_33,data_44,data_55,data_66,data_77,data_88,data_99,data_1010, '*');
    grid on
    xlabel('Time (sec)');
    ylabel('Extensional Viscosity (Pa-sec)');
% get current axes
axes1 = gca;
% now add color code
axes1.ColorOrder = [1 1 1;0 0 1;0 0 1;1 0 0;1 1 0];
